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.

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.
