[Gene Soo <genesoo77072@xxxxxxxxx>]

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.

  problem

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.
