[vbox-dev] SVN build and audio issues

[Andreas Löffler]

Hi Perry,

great, glad it works for you again, and thanks for doing some testing
using this (new) code path.

The plan is to have HDA support for (newer) Linux guests, so that those
can take advantage of features the AC'97 emulation does not support.
AC'97 definitely will stay around, but we didn't make up our minds yet
whether (and when) HDA will become the standard sound device emulation
for newly created guests.

Andreas
