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

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:

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

[Arie Skliarouk]

KVM on lucid appears to prioritize pa:
#kvm -audio-help | grep ^Name
Name: pa
Name: alsa
Name: sdl
Name: oss
Name: none
Name: wav

but in effect alsa is still used... could it be related to the fact that
by default pulse-audio daemon is started per user, whereas kvm starts
the virtual machines before user has a chance to login?

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

[Dave Walker]

The Debian big referenced suggested using ALSA over OSS, this bug is
related to favouring PA over ALSA.  The Debian issue was resolved with:

--- kvm-79+dfsg/debian/rules
+++ kvm-82+dfsg/debian/rules
@@ -141,7 +141,9 @@
 config.status: configure

 build-arch: patch config.status build-arch-stamp


However, the current debian qemu-kvm package contains:
                    --audio-drv-list="alsa oss sdl pa" \
                    --audio-card-list="ac97 es1370 sb16 cs4231a adlib gus hda" \


Neither of these configure options are set in debian/rules.  This probably requires further investigation.

Thanks.

[Serge Hallyn]

Can someone post a good test case, and expected and actual results at
this point?  Maybe an upstart job running

  kvm --audio-help  | grep ^Name

so that no user is logged in yet (per comment #14)?

[Clint Byrum]

Bump, fairly old issue here. I wonder if anybody is still affected on
recent releases of Ubuntu (including 10.04 but also 11.10 and precise.)
