I've tried: ICH6 - that was the orig default in the VM when created AC97 I cleared syslog - I changed to AC97 (shutdown vm and restarted it & verified it was now set to AC97) and got this in syslog which appears the SAME as with ICH6 despite having switch to AC97:
Nov 1 06:27:52 bmullan-virtual-machine pulseaudio[1799]: [alsa-sink-Intel ICH] alsa-sink.c: ALSA woke us up to write new data to the device, but there was actually nothing to write! Nov 1 06:27:52 bmullan-virtual-machine pulseaudio[1799]: [alsa-sink-Intel ICH] alsa-sink.c: Most likely this is a bug in the ALSA driver 'snd_intel8x0'. Please report this issue to the ALSA developers. Nov 1 06:27:52 bmullan-virtual-machine pulseaudio[1799]: [alsa-sink-Intel ICH] alsa-sink.c: We were woken up with POLLOUT set -- however a subsequent snd_pcm_avail() returned 0 or another value < min_avail. attached the /var/log/syslog of the AC97 vm start note it shows AC97 clocking messages but it the messages above still show [alsa-sink-intel ICH] maybe I don't understand that message but it looks like sound never changes from ICH even if virt-manager indicates it is AC97 ** Attachment added: "syslog for startup after switch to ac97 (and after having cleared /var/log/syslog" https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1246929/+attachment/3897592/+files/ac97-syslog -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1246929 Title: alsa bug in KVM virtual machines To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1246929/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
