The easiest way to reproduce (at least for me): start Firefox, play something on Youtube, close Firefox, restart Firefox, no sound for videos (or VLC player or aplay). Killing /usr/bin/pulseaudio fixes the issue until something is started and restarted again. grep -i pulseaudio /var/log/syslog contains following lines Sep 1 16:38:17 jasu pulseaudio[4574]: [pulseaudio] alsa-util.c: Disabling timer-based scheduling because running inside a VM. Sep 1 16:38:17 jasu pulseaudio[4574]: [pulseaudio] alsa-util.c: Disabling timer-based scheduling because running inside a VM. Sep 1 16:38:42 jasu pulseaudio[4574]: [pulseaudio] bluez5-util.c: GetManagedObjects() failed: org.freedesktop.DBus.Error.NoReply: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken. Sep 1 16:38:53 jasu pulseaudio[4574]: [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. Sep 1 16:38:53 jasu pulseaudio[4574]: [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. Sep 1 16:38:53 jasu pulseaudio[4574]: [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.
