Comment 14 for bug 1487168

Let me start out by asking an important question.
In the Generated Problem Report between Title and Bug Description is the
following statement.

Status in alsa-driver package in Ubuntu:
  Incomplete

Is Audio support code still under development for this Volume Slider
function or should it be working properly? If it is supposed to be working
then please continue reading this response.

I don't understand the points you are making by referencing the User Manual
and also pointing out differences in emulated vs native support for the two
chipsets.
You had included cryptic text that looks like it is logic from an XML file
or perhaps comments from program code. Later I will reference User Manual
text that has a slight mention to AC97 and nothing about AC98.

I can't tell whether the point(s) your trying to make

1) is that it working as designed and there is no problem.
2) or, You can get it to work if you make a change(unfortunately I can't
make out what change you are suggesting).

The following is contents from the Virtualbox User Manual I have at my
disposal regarding the customizable Audio Selection options:
3.7. Audio settings

The "Audio" section in a virtual machine's Settings window determines
whether the VM will see a sound card connected, and whether the audio
output should be heard on the host system.

If audio is enabled for a guest, you can choose between the emulation of an
Intel AC'97 controller, an Intel HD Audio controller[16
<https://www.virtualbox.org/manual/ch03.html#ftn.idp46785383838160>] or a
SoundBlaster 16 card. In any case, you can select what audio driver
VirtualBox will use on the host.

On a Linux host, depending on your host configuration, you can also select
between the OSS, ALSA or the PulseAudio subsystem. On newer Linux
distributions, the PulseAudio subsystem should be preferred.
====================================

If you have specific recommendations for options to try then please be
specific.
