Status changed to 'Confirmed' because the bug affects multiple users.

pulseaudio keeps crashing for me too on Zesty, maybe about once a day. It didn't happen in earlier releases.

When it crashes, volume controls (Fn+F2/F3 hotkeys on my laptop, and in Unity's upper panel) no longer work. Manually launching "pulseaudio --start" fixes the Unity panel's control, but does not fix the more convenient keyboard shortcuts. Logging out and back in fixes everything.

Seems to me that existing Firefox processes (or tabs? not sure) can still play sound when there's no pulseaudio running (no clue how), but newly opened ones cannot.

Let me know if there's anything I can help.

[Egmont Koblinger (egmont-gmail)]

I got so sick and tired of these frequent crashes and not being able to listen to music or adjust the volume that I ended up downgrading the pulseaudio packages using their Yakkety version (the rest of the system is Zesty). Everything's been fine since then.

See also bug #1689555. Not sure if a duplicate of this (probably it is), and provides an idea for reproducing the crash.

I tried to reproduce the crash with a terminal bell and failed.
