[Gene Soo <genesoo77072@xxxxxxxxx>]

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.

Title:
  [Emulated AD1980 AC97 inside Virualbox 5.0, playback] volume slider
  problem

Status in alsa-driver package in Ubuntu:
  Incomplete

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.
