With the upgrade to PulseAudio 7.0 on Archlinux, audio in Chromium 45 and other applications which use pulseaudio fail to work properly.

In the case of chromium, launching with the default sandbox and no profile/seccomp chomium will launch and instantly report a failure that it is unable to open a slave. Firejail worked fine on PulseAudio 6.

Aside from the debug output of firejail the only other noteworthy output that Chromium spews is the failure to open a slave, which I have found is something dealing with ALSA on the system.

A similar outcome can be observed when launching firefox with no profile, as well as any other application which may use pulseaudio.

Oddly enough, things like Steam work fine at outputting audio via Pulse, but seem to fail when attempting to record audio input via a microphone in firejail, even though this functionality was working under PulseAudio 6.

Apologies for the very vague bug report, I am rather confused about where the source of the problem exactly is.

Firejail version 0.9.30
PulseAudio version 7.0
