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.
