Comment 63 for bug 1487168

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.
