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? -- kvm: use PulseAudio instead of ALSA https://bugs.launchpad.net/bugs/393430 You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. Status in QEMU: Incomplete Status in “kvm” package in Ubuntu: Incomplete 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
