Bug Description
Volume Slider is only controlling PCM channel and is not controlling Master. In effect, Master is restricting the audio level to the default of approximately 45 Percent. In order to raise the Master Volume Level, alsamixer is capable of changing Master. Without manually raising Master to Max Volume, Volume Slider can only control volume from 0-45% which is the default level of Master.

I don't understand this response.
I am not an experienced programmer with respect to these platforms and have
no control what Virtual Box presents back to the OS.
I will say that this problem effects multiple distributions.
Particularly Kubuntu-KDE, Edubuntu, Lubuntu, & Xubuntu.
Luckily, the following distributions are not impacted, Ubuntu Gnome,
Ubuntu-Unity. Ubuntu-Studio.
If there is a interface problem between the Audio support software and
hardware/
owning groups.
I would recommend the development team research the differences of how
Audio is treated across the platforms that fail vs the ones that work.
I am sure there is differences and there is something going wrong in the
ones that are failing.
I would also guess that it is not likely that Virtual Box is the direct
cause because the list of work distros runs on the same Virtualbox platform
that serves the failing distros.

Lots of questions, I'll attempt to answer as best as I can.
First. Host OS Level:
uname -a
Linux gwsux79 3.13.0-62-generic #102-Ubuntu SMP Tue Aug 11 14:29:36 UTC
2015 x86_64 x86_64 x86_64 GNU/Linux
Second, Sound Card/Sound Support: I don't understand the question about
"Real Sound Card Support 5.1".
Onboard Audio Intel Motherboard DX79SI The following URL is documentation
for the Motherboard.
https:/
Third question asks Which Audio Backend is being used for VirtualBox 5.0?
I take the the defaults(Audio) for installing any Guest OSes. When I look
at the Settings for the guest I reported this issue, it lists
Host Driver: PulseAudio
Controller: ICH AC97
I hope this answers your questions.

I don't know how to proceed with the following recommendation:
"you can select the emulated hda and stac9221 hda codec"
When I get into the Audio Settings for this guest, I have two Pull Downs I
can control.
First is Host Audio Driver: Pulse Audio(Default), Null Audio Driver, OSS
Audio Driver, ALSA Audio Driver.
Second is Audio Controller: ICH AC97(Default), Intel HD Audio, Soundblaster
16.
I did some experimenting and was able to get the Slider to work correctly.
The change that I made was switching the Host Audio Driver from Pulse Audio
to ALSA Audio Driver.
I went back and reviewed the Audio settings for each of the Guest Distros
involved in this testing. All defaulted to Pulse Audio & ICH AC97. I don't
know if this is an issue with Virtual Box selecting the wrong driver to
default to or if design changes in Audio Support for Pulse Audio is now in
error. I can only compare between Unity Desktop, Ubuntu Gnome, and Ubuntu
Studio does support this default fine so I would guess that VirtualBox
support would argue this is an Host Audio issue.

Additional Comments regarding last change from Pulse Audio Driver to ALSA
Audio Driver.
Although this change did resolve the Volume Slider controlling both PCM and
Master output channels,
Extended playback using this driver causes instability in the playback
speed.
At first, the playback speed is normal but after a while, the playback
speed jumps up much faster. Somewhere on the order of 10 times normal.
Reboot of machine is not necessary to restore normal playback however I
would need to do additional longer testing to see whether Browser Reload of
webpage is enough to restore playback speed. I am inclined not to pursue
this testing unless I hear back that I must run on this ALSA Driver. I am
afraid that pursuing permanent run on this ALSA Driver would cause a
Multigroup Support issue involving your team as well as VirtualBox Support.

Testing Results for Kubuntu-KDE 15.10 Distribution.
Original Problem report was issued from Edubuntu 15.10 Daily.
I tried switching the Virtualbox Audio Hardware Driver from Pulse Audio to
ALSA Audio consistent with results for the Edubuntu distribution.
Monitoring alsamixer for Channel levels, using the Volume Slider on KDE
does not Control the Master Audio out channels.
I performed similar changes to my Lubuntu and Xubuntu Guests and received
the same results as Kubuntu-KDE.
To Restate, the only Distribution that I have a workaround to restore
proper Volume Slider Control is Edubuntu.
Altering Virtual Box Hardware Audio Drive from Pulse Audio to ALSA Audio
has no effect on correcting Volume Slider's lack of controlling Master Out
Channel(s) for Kubuntu-KDE, Lubuntu, & Xubuntu..

Let me start out by asking an important question.
In the Generated Problem Report between Title and Bug Description is the
following statement.
Status in alsa-driver package in Ubuntu:
Incomplete
Is Audio support code still under development for this Volume Slider
function or should it be working properly? If it is supposed to be working
then please continue reading this response.
I don't understand the points you are making by referencing the User Manual
and also pointing out differences in emulated vs native support for the two
chipsets.
You had included cryptic text that looks like it is logic from an XML file
or perhaps comments from program code. Later I will reference User Manual
text that has a slight mention to AC97 and nothing about AC98.
I can't tell whether the point(s) your trying to make
1) is that it working as designed and there is no problem.
2) or, You can get it to work if you make a change(
make out what change you are suggesting).
The following is contents from the Virtualbox User Manual I have at my
disposal regarding the customizable Audio Selection options:
3.7. Audio settings
The "Audio" section in a virtual machine's Settings window determines
whether the VM will see a sound card connected, and whether the audio
output should be heard on the host system.
If audio is enabled for a guest, you can choose between the emulation of an
Intel AC'97 controller, an Intel HD Audio controller[16
<https:/
SoundBlaster 16 card. In any case, you can select what audio driver
VirtualBox will use on the host.
On a Linux host, depending on your host configuration, you can also select
between the OSS, ALSA or the PulseAudio subsystem. On newer Linux
distributions, the PulseAudio subsystem should be preferred.
=======
If you have specific recommendations for options to try then please be
specific.

Last Update for tonight.
I understand it is monumentally difficult to support all of the varieties
of hardware that exist and because of that, I make myself available to test
or provide information for my specific operating environment.
For the most part, I expect that the OS packages that I install ask for
customary user input like names, passwords, and the like.
I do not expect to have to supply or know details about my specific
hardware other than gross features like memory allocations, number of
processors and similar things.
I have identified an Audio Problem that effects specific Ubuntu
Distributions currently under development and also identified related
distributions in the same Ubuntu Family that does not have this problem
with the same VirtualBox running on the same hardware platform.
Besides the Ubuntu distributions, I also run various other Linux
distributions, OpenSUSE, Linux Mint, Fedora, Oracle Linux, Windows 10
Technical Preview.
I have not experienced anything like this on any of the other Guest OSes
that I just listed
If you have additional information requests, I will be happy to try and
supply whatever you ask.
If you have possible workarounds or code solutions, I will happy to try
them .
If we need to get VirtualBox involved in debugging the problem, I will be
happy to work with their representatives.
Otherwise, I will track this issue and hope that some day it gets resolved.

I believe I have discovered the cause of the problem.
Your prompting me to look at the Open Issues for VirtualBox pointed out
that I was on V5.0.0 and when I went to the Downloads Page, V5.0.2 was
currently available.
VirtualBox will send a push notification when the team indicates and
important release is available and is displayed when you start VirtualBox.
Although 5.0.2 is generally available, they did not mark it for Push
Notification.
I upgraded to 5.0.2 and also followed through with a process called Install
Guest Additions, that led to more serious errors.
The Guest Additions Scripting installs custom support for a variety of
system dependent things including advanced Video capabilities like Screen
resizing.
I had noticed this issue before but was not zoned in on it because it is a
critical failure for the new KDE Distro and not with the other Desktops.
I decided to backoff to VBox V4.33 which is the latest release for V4 of
VirtualBox.
Spot checking all of the 15.10 Distros having this audio problem, just
getting into alsamixer and adjusting the Volume Slider, they seem to work
correctly with VBox V4.33.
The VirtualBox Team had a V5.0.3 release that hasn't been finalized but is
available for users to manually install. I have not tried that release to
see if the Audio issues are resolved.
I need to turn my attention to reporting both this Audio Issue and the
Video issue to the respective Virtual Box teams.
I believe you can mark this issues as Closed.
Thanks for all of the help in getting this issue sorted out.

Correction to last comments concerning problem resolution.
I inadvertently referred to backing off from Version 5.0.2 to VirtualBox
Release 4.33.
The correct backoff release number is 4.3.30-101610.

Miscellaneous Control Bit Register (Index 76h)
bit14 AC97NC
AC ’97 No Compatibility Mode.
This bit allows the surround, center, and LFE volume control registers and output attenuators to operate in a more functional mode than defined by the AC97 2.2 spec. This is called ADI compatibility mode. In AC ’97 compatibility mode, the DAC Gain/Attenuators for the surround, center, and LFE are controlled by Register 18h (PCM volume). The output pin attenuators for the surround are controlled by Register 38h, and the output pin attenuators for the center and LFE are controlled by Register 36h. In ADI compatibility mode, the Surround DAC Gain/Attenuators are controlled by Register 38h, and the Center/ LFE DAC are controlled by Register 36h. The output pin attenuators for Center/LFE are controlled by Register 02h (Master Volume), and the output pin attenuators for Surround are controlled by Register 04h.
0 = AC97 compatibility mode (reset default).
1 = ADI compatibility mode.

bit 5 LOSEL
LINE_OUT Amplifiers Input Select.
This bit allows the LINE_OUT output amplifiers to be driven by the mixer or the surround DACs. The main purpose for this is to allow swapping of the front and surround channels to make better use of the SURR/HP_OUT output amplifiers. This bit should normally be used in tandem with the HPSEL bit (see below).
0 = LINE_OUT amplifiers are driven by the mixer outputs (reset default).

You made a lot of updates to this record and I cannot tell whether or not
you hit on issues that requires coding changes on the Ubuntu Audio side.
I did want to report that I seem to have found a resolution that I am
satisfied with.
To summarize, I mentioned that after backing off from Virtual Box 5.0.2 and
installing Virtual Box 4.3.30, my audio problems were resolved and I was
able to use the Volume Slider in order to control the Volume. After
contacting the Virtual Box team, they gave me a customization option change
to correct the video problems I was experiencing that did not relate to
this audio problem. Since that customization option solved the video
problem, I wanted to go back and reinstall VBox 5.0.2 to see if the Audio
problems persist.
Short answer is No, they did not exist under a fresh install of 5.0.2. I
speculated to the VBox team that I perceive the Maintenance upgrade from
VBox 5.0.0 to 5.0.2 did not work completely correct. The fact that I
performed a full uninstall of VBox going to the older 4.3 level and to the
current 5.0 levels both had the audio working correctly. I can only assume
the service upgrade process was the cause.
Please close this record as resolved at your earliest convenience.

*Refer to Table II for examples. This register controls the Mono output volume and mute bit. The volume register contains five bits, generating 32 volume levels with 31 steps of 1.5 dB each. Because AC ’97 defines 6-bit volume registers, to maintain compatibility, whenever the D5 bit is set to “1,” their respective lower five volume bits are automatically set to “1” by the codec logic. On readback, all lower five bits will read “1s” whenever this bit is set to “1.” All registers not shown and bits containing an X are assumed to be reserved.

I discovered that the Volume Slider problem exists even after the clean
install of Virtual Box 5.0.2.
I have screenshots that document the errant behavior.
I am not used to submitting documentation for problems other than typing in
descriptive text when prompted.
Can I attach the screenshot files as attachments to one of these emails and
will they be posted in your problem tracking application?
If not, can you direct me to instructions on how to submit documentation?

First, you dd not answer my question on whether or not I could attach the
files directly to this email and whether you would be able to get them or
do I need to upload them somewhere?
Second, I want to clarify the Verbose Log you want. Is that the Log from
Show Log CTRL+L? If so, I assume you want all of the available logs so you
can see from installation to last boot?
Third, I don't understand the last sentence starting with "the linux driver
check" nor do I know what to make of the URL you sent. If the sentence is
supposed to give me instructions to do something in relationship to the URL

I'll attempt to describe the patterns and symptoms I am noticing and with a
subsequent email attach ScreenShot files to support those observations.
With this latest round of testing the Ubuntu 15.10 daily drops, most of
the distributions are behaving correctly in that Volume Slider does control
volume levels correctly adjusting channels Master and PCM.
alsamixer reports Card: Intel 82801AA-ICH
Chip: Sigmatel STAC9700,83,84
The two distributions I am having problems with is.
Distribution: Lubuntu 15.10
*Volume Slider Controls Master Only and Not PCM.*
alsamixer reports same Card and Chip information as above however the
Volume Slider
Distribution: Mate 15.10(Had Not Previously tried this Distribution)
Volume Slider Only Controlling PCM and Not Master This Symptom was common
in the previous testing when more distributions were effected however I am
not sure that the Chip identified below was the same in those past tests.
alsamixer reports Card: Intel 82801AA-ICH
Chip: *Analog Devices AD1980*
On my next update, I will attach all of the Screenshots and Vbox Logfiles
for the failing machines.

Regarding this update and the previous update referencing a Verbose VBox
Log.
Trying to find out what a Verbose Log is or how to activate Verbose
logging, I looked for Verbose in the user manual and got hits in Chapter 8
of
the User's manual. I see references to VBoxmanage command syntax. It is
not obvious that any of these commands turns on Verbose logging in general.
Are you expecting me to issue one or a series of these commands or is there
another location where a verbose log is kept other than what I supplied?
if you are unable to answer this question, I will have to work with the
VirtualBox Team.
Second item is the patch you referenced. The link supplied is to C source
code. I cannot find references on what to do in order to compile this code.
I did see that there was a process to create a Source Code Fork in order to
be able to compile the entire forked copy of the source.
Are you telling me to follow those steps and substitute this version of
that module and try testing again?
Another question is the observation made about Dell. I own a Dell Laptop
however the platform that runs my Virtual Box testing environments is a
self constructed machine based off of Intel DX79SI Motherbpard and a Intel
Xeon Processor. In other words there are No Dell Branded parts in this
machine. What does the reference to Dell mean?

I went ahead and followed documentation on the VirtualBox Forum to fork the
current VirtualBox Source. I believe that I have resolved all of the
installation errors that were due to errors in the packaging and
obsolescence of packages in the Ubuntu Release I am running on. i have not
attempted to install this package because it will require me to Uninstall
the supported version of VirtualBox. I will shutdown for now to await
answers to past clarification questions.
I need answers to What is the proper way to obtain Verbose Logging in
VirtualBox?
Do I need to Fork The VirtualBox Source in order to use the Patch code sent
to my via URL?
An additional question clarifying the quote below, Is there a code change
required to the Patch because of the "prevent swap" comment?
If the answer is Yes, I need specific editing instructions on the code that
needs to be changed or if you send me the modified version, I can try and
assemble it.
"since it hardcode ad1980 on a dell machine, *you may need patch in alsa*
*driver* to prevent the swap of the master playback volume/switch and
headphone playback volume/switch"
Again, I am not proceeding with any further testing or implementation of
the Forked Testing environment without answers to above questions.

I am not an experienced programmer with respect to these platforms and have
no control what Virtual Box presents back to the OS.
I will say that this problem effects multiple distributions.
You should study the ad1980 datasheet
take a look at the functional block diagram
there is an ac97 mixer which mix the Front DAC signal ( controlled by PCM Out Volume) and other analog input sources (CD , Mic , Line In, stereo mix playback volume)

I'm sorry, I don't know how to proceed with this issue.
Early on, you asked for Verbose Logging from Virtualbox. I supplied the
Machine Log for the failing Guest and I knew Verbose was probably Defaulted
to Off.
Since then, I have found the commands to change the running machine
"VBoxManage debugvm" however the VirtualBox Documentation is weak on
descriptions and examples of how to turn on the Verbose logging for Audio
issues. I can see in some of their supporting Code Snippets that Group 2
Logging maybe applicable. I cannot find any "VBoxManage debugvm" examples
controlling setting verbose by group.
I am also having difficulty in understanding what coding changes needs to
be done in order to address your last couple of updates.
So here is the difficulties I am facing.
I would feel more comfortable if we pursued tracing the problem rather than
making code changes.
If you are unable to direct me toward specifying the correct commands to
accomplish this then I can try getting help from the VirtualBox Forum site.
I will say they have not been very helpful so far regarding this issue.
Short of these two options, I am prepared to drop the issue entirely and
someone else with the same problem and is better up to speed with working
with this code and these tools can pickup the effort.

you need to log all i/o ports read/write of those ich controller registers and ac97 codec registers read/write
since real dell dimension 8400 ad1980 support 5.1 but using ich6 controller
the emulated ich controller only support stereo

- U1510LUDLY Alsamixer 1 After First Boot.png.zip Edit (1017.9 KiB, application/zip; name="U1510LUDLY Alsamixer 1 After First Boot.png.zip")
LocutusOfBorg, I am in desperate need of help on this issue in several
areas.
I would have hoped this would have been much easier to report and let you
experts work the issue however even though I can describe what I am seeing,
it is very difficult to supply the respective folks with enough
documentation to take over. I am a mainframe programmer so I understand
parts of this but not familiar with coding and debugging on this platform.
I've tried to communicate to Raymond that I do not know the proper command
syntax to perform Verbose Logging. I did see a reference to "all" in some
of the documentation however near that reference, it was clearly stated
that you probably don't want to do that. If you can let me know, the
VBoxManage debugvm commands that would be appropriate to figure out Audio
Problems, I would really appreciate it.
As to your offer of supplying latest patched to your ppa, I would take you
up on that offer however I need help with the proper commands to get those
changes into my environment. Not knowing all of the terminology, I was able
to run the SVN commands to establish a development fork on my Test system
obtained from the FAQs from the VirtualBox Forum. I have not gone into
intensive study into making updates of any of the downloaded files and what
it takes to recreate the final installation package. Last night, I removed
the VirtualBox Directory and recreated it followed by rerunning all of the
SVN, and subsequent commands(make, KMK, etc) to get the latest code. I was
able to bring up a fresh copy of VirtualBox. *If you can confirm that If I
make a source code change and repeat all commands starting with the first
Make, that is the proper steps to get that change compiled and integrated
into the test package?*
A supplemental comment to Raymond about this, You are making references in
your responses that it is easy switch to Intel HDA from emulated AC97 as a
workaround.
I went into VBox Guest Settings and made this change for the two remaining
distributions having the problem(Lubuntu and Mate).
I am attaching a Zip file of Screen Snapshots. To summarize on Lubuntu,
Slider Level defaults to Below Max level(Only controlling Master channel)
with MAXed and MINed Slider settings confirming only Master channel Level
being controlled. On Mate, The Slider Defaults at Max Level which is
inconsistent with the Master Channel Level reported by alsamixer. Then when
I MINed the Slider, the only channel that seemed to be effected was S/PDIF.
Moving the Slider did not change the Master or any of the Headhone/Speakers
channels.
This setting seems to be worse than the ICH AC97 setting.

ALSA: hda - Halve too large volume scales for STAC/IDT codecs
STAC/IDT codecs have often too large volume scales such as -96dB,
and exposing this as is results in too large scale in percentage
representation.
This patch adds the check of the volume scale and halves the
volume range if it's too large automatically.

I have no idea what "the output of alsa-info.sh" is. Is this some sort of
Shell script that needs to be run?
If so, when do you run it,
a) One time only,
b)Before changing the Slider Position,
Giving me these short segments of details without specific instructions is
causing me to give up on pursuing this issue as not being able to be fixed
because it is taking too long to get you sufficient documentation to work
the issue.

My interpretation of this update is that I believe you are trying to
suggest that I apply this patch to correct a scaling problem with HDA,
Is that what you are trying to communicate?
Also, I understand that this code is or maybe broken but why are we working
on Intel HDA when the default ICH AC97 seems to have the problem. I would
rather work on getting the defaulted Driver correct.

If you can compile directly from svn it is already great, otherwise if you want to
build the debian package you can just apt-get source virtualbox, enter the directory
and dpkg-buildpackage it to create the binaries.
It is up to you :)
BTW did you try the Debug switch?
Build type:
-d, --build-debug build with debugging symbols and assertions
it is listed in configure script.
cheers,
G.

NO, the change of enumerated ac97 codec from stac9200 to ad1980 in virtualbox is the main cause of the problem
unfortuately enable log by dev_ac97 still not sufficient to produce useful debug info
you need to recompile alsa driver by adding those dev_info to dump the values of ac97 codec registers read/write
the worst thing is the ad1980 in dell imension 8400 did not work in the above bug report,
it is not clear how headphone and line out use/share volume control
