[Qemu-devel] [Bug 393430] Re: kvm: use PulseAudio instead of ALSA

[Dustin Kirkland <dustin.kirkland@gmail.com>]

Hmm, I think upstream does prioritize pa over alsa.  Marking incomplete,
need to check that.

Bug description:
Binary package hint: kvm

kvm in jaunty prefers to use OSS drivers rather than ALSA:
# dpkg -l | grep kvm
ii  kvm            1:84+dfsg-0ubuntu11            Full virtualization on i386 and amd64 hardwa
# kvm -audio-help | grep ^Name
Name: oss
Name: alsa
Name: sdl
Name: pa
Name: none
Name: wav
#

Because of that, once a virtual machine with working audio card starts, the kvm grabs the audio card entirely for itself. Any subsequent operations on audio card either from the host machine, or from the other audio-enabled virtual machines lock up (apparently awaiting on on access to the audio card).

The bug is echo of the corresponding debian bug:
