Title:
kvm: use PulseAudio instead of ALSA
Status in QEMU:
Invalid
Status in “kvm” package in Ubuntu:
Fix Released
Status in “kvm” package in Debian:
Fix Released
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:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=508018
