ALSA info gzipped

I basically have a generic Dell box with integrated ICH7 audio

 0 [ICH7 ]: ICH4 - Intel ICH7
                      Intel ICH7 with AD1981B at irq 23

When I plug my headphones into the front, in alsamixer only the Headphone slider has an effect, Master does nothing to change volume.

Now Pulseaudio somehow merges these (even if flatvol is off) and the whole range of Headphone is compressed into the low range and it gets painful very quickly.

No idea if this is ALSA bug or not. Please advise and forward accordingly.

Have you had time to look at this yet, Maarten?

You've told me to poke you.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Colin Guthrie (launchpad-colin)]

I think this is expected behaviour...

Can you attach output of "pacmd ls"?

Normally I'd expect a "Headphones" port to be available for your Sink. With the jack detection capabilities added in PA 2.0, this port will hopefully now be activated automatically when a jack is plugged in. In older versions you have to enable the port manually in pavucontrol or another mixer when you plug in a jack.

pacmd ls

Attached »pacmd ls«. (Note I have an Apple Monitor with USB audio too)

It’s not expected behaviour that when I use my volume buttons that only the two lowest ticks give me a range between threshold-of-hearing and thresold-of-pain, is it?

 |0---xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx|

0 nothing, x == pain

I don’t have a headphone port. It’s not there. And on IRC mkbosman told me he had the same problem and to open this bug.

Plain version of alsa-info for better readability.

[Colin Guthrie (launchpad-colin)]

You appear to have two Headphone related ports available along with a couple others:
 * Headphones / Amplifier
 * Headphones / No Amplifier

ports:
 analog-output-headphones;output-amplifier-on: Headphones / Amplifier (priority 9010, available: unknown)

 analog-output-headphones;output-amplifier-off: Headphones / No Amplifier (priority 9000, available: unknown)

 analog-output-lfe-on-mono;output-amplifier-on: LFE on Separate Mono Output / Amplifier (priority 4010, available: unknown)

 analog-output-lfe-on-mono;output-amplifier-off: LFE on Separate Mono Output / No Amplifier (priority 4000, available: unknown)

What is interesting is that you do not have any "Analog Speakers" ports listed. I think we're addressing this shortly in PA master having spoken to David (I can tell you're using Ubuntu from the patches), so this is good, but I'm not sure why Master is getting adjusted here... I'd have expected the two headphone ports to adjust Headphones and Line respectively.

Ultimately, this basically boils down to writing a profile for the hardware. I'd have hoped the default profiles would have sufficed and perhaps it still can once the speakers port comes in.

For more info on writing profiles see:
http://www.freedesktop.org/wiki/Software/PulseAudio/Backends/ALSA/Profiles

I've CC'ed David to get his input here.

That's an ALSA driver bug. Unfortunately I don't know how to fix AC'97s.

> What is interesting is that you do not have any "Analog Speakers" ports listed.

There does not seem to be any kcontrols indicating that you have speakers, therefore no "Analog Speakers" port.

It seems to me that if "Master" controls the speaker but not the headphones, "Master" should be renamed to "Speaker".

[Arun Raghavan (arunraghavan)]

What needs to be done here? ALSA-side fix?

[Raymond (superquad-vortex2)]

PCM Playback volume of a two channels AC97 Codec is just similar to the virtual master volume of HDA codec

[Sigman (sigman32)]

I run alsa-info.

Headphones produce sound, however there is no sound from internal speaker.

At /etc/modprobe.d/alsa-base.conf I added this line:

options snd-hda-intel model=mobile

it didn't help as I found out later that snd_intel8x0 is in use.

[Raymond (superquad-vortex2)]

https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1078704/comments/5

without the headphone plugged in
 0:72 = 0804

with the headphone plugged in
 0:72 = 080c

it is possible to add Jack detection support on some AC97 codec

[Sigman (sigman32)]

I just remembered something that might be important.

When I had ubuntu 12.04, 12.10 and 13.04 I could use internal speaker. Once I upgraded to 13.10 I am not sure.

That old pc uses my father and he says that it stopped working out of sudden.

And last thing I did is Upgrade to 13.10.

I cannot test it with Live CD now, But I will try it as soon as I can.

[9-mc-o (9-mc-o)]

It seems that I have same problem here.
It's Dell Optiplex GX620 + fresh 13.10 install.

I have only 2 output ports in pulseaudio

        ports:
                analog-output-headphones;output-amplifier-on: Słuchawki / Amplituner (priority 9010, latency offset 0 usec, available: unknown)
                        properties:
                                device.icon_name = "audio-headphones"
                analog-output-headphones;output-amplifier-off: Słuchawki / Brak amplitunera (priority 9000, latency offset 0 usec, available: unknown)
                        properties:
                                device.icon_name = "audio-headphones"

So I cannot get any output from motherboard ports (headphone port is also too loud as somebody mentioned).

My alsa-info is at
http://www.alsa-project.org/db/?f=e1ab95695370eaa14f1c47947e1a2a0a3232d2f0
(there's also nvidia card with intel-hd hdmi stuff inside)

Please tell me if I can provide any additional useful info to fix this.

[Neil (kingfisher)]

Its the same with 14.04, 14.10 and 15.04, is support discontinued for Dell GX600, It would be nice if someone with expert knowledge would explain how the internal speaker can be correctly detected, after all it all worked perfectly in 12.04

MASTER VOLUME REGISTER Index 0x02

 This register controls the Line_Out volume controls for both stereo channels and the mute bit. Each volume subregister 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 or D13 bits are set to 1, their respective lower five volume bits are automatically set to 1 by the codec logic. On readback, all lower five bits read 1s whenever these bits are set to 1. Refer to Table 12 for examples.

this is quite different from those virtual master of hda codecs

[Raymond (superquad-vortex2)]

you have to provide pulseaudio verbose log and

pactl list sink

if line out use master playback volume and headohone use headphone playback volume

you need to use customised pulseaudio conf files

https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/893210

it is unlikely fix in alsa driver as pulseaudio expect jack detection kctl

although js0 ST or js1 ST of ac97 register 0x72 of ad1981b may reflect hp status

it is not clear how and when to check the change in jack state by timer or interrept

[Raymond (superquad-vortex2)]

Table 40. Bit Mnemonic JS0 Interrupt Function JS1 TMR JS0 TMR JS1 MD JS0 MD JS1 ST JS0 ST JS1 INT JS0 INT 0x0000

JS1INT JS0ST JS1ST JS0MD JS1MD JS0TMR JS1TMR JS0EQB JS1EQB JSMT [2:0]

JS0INT
This bit indicates that Pin JS0 has generated an interrupt. This bit remains set until the software services the JS0 interrupt, that is, JS0 ISR should clear this bit by writing a 0 to it. The interrupt to the system is an OR combination of this bit and JS1INT. The actual interrupt implementation is selected by the INTS bit (Register 0x76). It is also possible to generate a software system interrupt by writing a 1 to this bit.

Js1 Interrupt
This bit indicates that Pin JS1 has generated an interrupt. This bit remains set until the software services the JS1 interrupt, that is, JS1 ISR should clear this bit by writing a 0 to it. See the JS0INT description for details.

JS0 State
This bit always reports the logic state of the JS0 pin.

JS1 State
This bit always reports the logic state of the JS1 pin.

JS0 Mode
This bit selects the operation mode for the JS0 pin. 0 = Jack sense mode (default). 1 = Interrupt mode.

JS1 Mode
This bit selects the operation mode for the JS1 pin. 0 = Jack sense mode (default). 1 = Interrupt mode.

JS0 Timer Enable
If this bit is set to 1, JS0 must be high for >278 ms to be recognized.

JS1 Timer Enable
If this bit is set to 1, JS1 must be high for >278 ms to be recognized.

 JS0 EQ Bypass Enable
This bit enables JS0 to control the EQ bypass. When this bit is set to 1, JS0 = 1 causes the EQ to be bypassed.

JS1 EQ Bypass Enable
This bit enables JS1 to control the EQ bypass. When this bit is set to 1, JS1 = 1 causes the EQ to be bypassed.

JS Mute Enable Selector

These three bits select and enable the jack sense muting action (see Table 41

 AC97_SINGLE("Line Jack Sense", AC97_AD_JACK_SPDIF, 12, 1, 0),
};

these two controls only change JSMT2 and JSMT1

you need bit 2 and bit3 of AC97_AD_JACK_SPDIF for JS0 ST and JS1 ST

create hp jack kctl similar to

the point is when do the driver call snd_jack_report by interrupt or timer

[Raymond (superquad-vortex2)]

http://cgit.freedesktop.org/pulseaudio/pulseaudio/tree/src/modules/alsa/mixer/paths/analog-output-headphones.conf

Thank you for your reply Raymond, i am uncertain what you are asking me do.

14.04, 14.10 and 15.04 sound settings output look like this:

and the associated alsa mixer controls e.g. speaker are missing

this is what 12.04 looked like and worked:

in working 12.04

  the name of the port change since pulseaudio try to remove reduant path

if you look at the functional block diagram, the headphone path and line out path have only two volume controls

pcm + headphone

and

pcm + master

pulseaudio just keep PCM at 0dB as Element PCM is defined in analog-output.conf.common

so the effective dB range of headphone is -46.5 dB to 0 dB

[Raymond (superquad-vortex2)]

ftp://ftp.alsa-project.org/pub/manuals/intel/

refer to ac97 2.1/2.3 specification

Figure 16. AC ‘97 Mixer Functional Diagram

master volume control line out
headphone volume control hp
master mono volume control mono out

[Neil (kingfisher)]

so how can I get pactl list sinks to include:

analog-output-lfe-on-mono;output-amplifier-on: LFE on Separate Mono Output / Amplifier (priority: 4010)
analog-output-lfe-on-mono;output-amplifier-off: LFE on Separate Mono Output / No Amplifier (priority: 4000)

do your gx620 have any mono output ?

do you mean the internal speaker is using mono out, you have to ask pulseaudio developer ?

I don't know Raymond. I just booted from ubuntu-12.04.5-desktop-amd64.iso, played a music file, opened alsamixer, and discovered that; changing Master M volume independently changed the internal speaker volume. In 14.04 Master M is muted by default, unmuting and raising the volume has no effect.

[Raymond (superquad-vortex2)]

http://cgit.freedesktop.org/pulseaudio/pulseaudio/tree/src/modules/alsa/mixer/paths/analog-output-headphones.conf

it is because headphone port mute master mono

[Element Master Mono]
switch = off
volume = off

as only snd-hda-intel implement jack detection kctl

those snd-intel8x0 does not have any jack detection kctl

[Raymond (superquad-vortex2)]

24 OUT (0) OUT (0) 1 1 0 FMUTE FMUTE ACTIVE JS0 mutes Mono; JS1 mutes Mono and Line-Out.
25 OUT (0) IN (1) 1 1 0 FMUTE ACTIVE FMUTE
26 IN (1) OUT (0) 1 1 0 ACTIVE FMUTE FMUTE
27 IN (1) IN (1) 1 1 0 ACTIVE FMUTE FMUTE

the other thing is that you have change mute enable selector to 110 which mute mono when you have line out or hp plugged

[Raymond (superquad-vortex2)]

try to set those ac97 registers 0x72 by turn off headphone jack sense and line jack sense control

http://cgit.freedesktop.org/pulseaudio/pulseaudio/patch/src/modules/alsa/mixer/paths?id=ba0203c4c0938fd646cf559456e3d691fc889029

do you mean regression of this patch ?

you have to open another pulseaudio bug report

[Neil (kingfisher)]

changed analog-output-headphones.conf
[Element Master Mono]
switch = on
volume = on
No effect

turned off headphone jack sense and line jack sense control
no effect, and were re-enabled by rebooting

Do not know how to implement the details in your post #43

just as an experiment I temporarily replaced the /usr/share/pulseaudio/alsa-mixer/paths/ directory with the one from 12.04
and that made no difference either!

Hi, I am also trying to get internal speakers to work on Dell OptiPlex GX620 (model no.: DCCY). External speakers work, however internal speakers are not even listed in PulseAudio Volume Control (and there is no sound). The internal speakers worked on previous OS (Windows XP).

If you need another test system, please let me know what to run. I would really like to make this work.

do you mean your desktop have stereo internal speakers since ad1981b only has three output

line out
hp
mono out

and your dell gx520 seem have hp at front and line out at rear

you have to add element master mono to speaker.conf

there appears not to be a speaker.conf
there is;
/usr/share/alsa/cards/PC-Speaker.conf
/usr/share/pulseaudio/alsa-mixer/paths/analog-output-desktop-speaker.conf
/usr/share/pulseaudio/alsa-mixer/paths/analog-output-speaker.conf
/usr/share/pulseaudio/alsa-mixer/profile-sets/force-speaker.conf

you also need to implement headphone jack and line out jack detection kctl and internal speaker phantom jack using bit 2 and bit 3 of AC97_AD_JACK_SPDIF register

Need your guidance, do not know how to implement

[Raymond (superquad-vortex2)]

ac97 patch only create hp jack kctl, line out jack kctl and internal speaker phantom jack

BUT still missing the most important part which the driver need to check the status of the jack by interrupt or timer periodically or just call once when pcm start playback

the conf file of three path should only contain the element which affect the path

speaker.conf require master mono expect
lineout.conf require master
headphones.cons require headphone

pulseaudio use conf to find out element require for the path and turn off the other element

[Raymond (superquad-vortex2)]

you will also need to schedule the driver to call ad198x_handle_hp_jack and ad198x_handle_lo_jack in intel8x0.c periodically similar to hda vt1708 codec

have you patch ac97 codec ?

you need ac97 codec create three jack detect kctls for [Jack Headphone] , [Jack Line Out] and [Jack Speaker Phantom]

the avaliablity of the port is determined by those jack detect kctls

post the output of alsa-info.sh

[Raymond (superquad-vortex2)]

https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1078704

however ad1981b is also used in notebook or desktop

this mean that you need to differentitate desktop and notebook

most likely you need pulseaudio to adjust the element in speaker path in alsa-mixer.c if notebook use master for the speaker

[Neil (kingfisher)]

no sorry, still trying to figure out what goes where!

[AndrewGX620 (andrewgx620)]

Sorry for late reply Raymond, I missed this post... :(

To clarify: I have an audi jack at front and another at the back. Both work if I plug some speakers in them. But this computer also has some internal speakers (sorry, don't know if they are mono or stereo - how can I find that out? I don't have WinXP anymore...) - these internal speakers don't show up in PulseAudio Volume Control.

I was messing around with it some more... If I put this in /lib/udev/rules.d/90-pulseaudio.rules:
ATTRS{subsystem_vendor}=="0x1028", ENV{PULSE_PROFILE_SET}="force-speaker-and-int-mic.conf"
or:
ATTRS{subsystem_vendor}=="0x1028", ENV{PULSE_PROFILE_SET}="force-speaker.conf"
... then I see the internal speakers in volume control (and additional controls in Gnome Alsa mixer), but I still can't get any sound from them.

> js1 st and js0 st seem to be clear , mono out is not muted by FMUTE

I have no idea what you mean? Also, are the patches meant to be applied at kernel sources? Sorry for noob questions, but I have zero experience in audio programming (or setup for that matter)... Would appreciate some pointers on how to apply your suggestions.

another problem is external amplifier defined in

[Element External Amplifier]
switch = select

[Option External Amplifier:on]
name = output-amplifier-on
priority = 10

[Option External Amplifier:off]
name = output-amplifier-off
priority = 0

you have to determine it affect which output paths

[Raymond (superquad-vortex2)]

http://cgit.freedesktop.org/pulseaudio/pulseaudio/tree/src/modules/alsa/mixer/paths/analog-output.conf

Intended for the 'default' output if your ac97 codec does not have headphone

when your desktop have three ports, you need jack detect kctl for each port

but element in analog-output.conf affect line out only and does not affect the desktop speaker

[Raymond (superquad-vortex2)]

add headphone, line out, speaker phantom jack detect kctl

rename Master to LineOut
rename Master Mono to Speaker

you may need to change system id if you are using gx520

AC97 Codec Information
----------------------

card*/codec97#*/ac97#?-?
 Shows the general information of this AC97 codec chip, such as
 name, capabilities, set up.

card*/codec97#0/ac97#?-?+regs
 Shows the AC97 register dump. Useful for debugging.

 When CONFIG_SND_DEBUG is enabled, you can write to this file for
 changing an AC97 register directly. Pass two hex numbers.
 For example,

 # echo 02 9f1f > /proc/asound/card0/codec97#0/ac97#0-0+regs

[Neil (kingfisher)]

cat /proc/asound/card0/intel8x0

[Raymond (superquad-vortex2)]

 AC'97 codecs ready : primary
 AC'97 codecs SDIN : 0 0 0

card*/codec97#0/ac97#?-?+regs
  Shows the AC97 register dump. Useful for debugging.

 recompile alsa driver with CONFIG_SND_DEBUG is enabled, you can write to this file for
  changing an AC97 register directly.

Pass two hex numbers.
  For example,

 # echo 02 9f1f > /proc/asound/card0/codec97#0/ac97#0-0+regs

this change master playback volume register

with headphone unplugged

set js1 mode bit of ac97 register 0x72

echo 72 1824 > /proc/asound/card0/codec97#0/ac97#0-0+regs

plug headphone

cat /proc/asound/card0/intel8x0

check bit 0 of global status is set or not

repeat the test with line out by set js0 mode

if gpi bit of global status was set after jack is plugged

we need to add a check of this bit in snd_intel8x0_interrupt and call those ad198x_handle_jp_jack
