[Qemu-devel] [HACK] hda: expose microphone instead of line-in

[Jan Kiszka]

Hi Gerd,

I had problems with Windows LiveMeeting expecting a microphone as
input. But the HDA model only exposes a line-in port. The following hack
works for me, but I bet there is a cleaner solution. Any suggestions?

BTW, sound output quality of a Win7 guest on my Linux hosts sucks while
it's fine for a Linux guest. I vaguely recall that Windows requests a
too small DAC buffer, is that true? Is there anything one can do about
this?

Jan
