[Pkg-pulseaudio-devel] Bug#574592: pulseaudio: alsa plugin makes firefox hang or sound go away

[Johannes Rohr]

Package: pulseaudio
Version: 0.9.21-1
Severity: normal

I have create a "pulse" alsa device which is default for all apps using alsa.

Very often when the system is under load, the sound in firefox (flash, youtube
etc) just goes away, and in order to restore it, I have to kill the firefox
client in paman. 

What also happens extremely often is, that somehow firefox freezes and cannot
even be killed and the only way to unfreeze it is again to fire up paman and
kill the firefox client, which of course terminates sound output, so some more steps are required to get sound back. 

Sound output from firefox/flash will reproducibly fail after suspend/resume.
