pulseaudio continually locks up my GNOME desktop

Reported by: jstedfast Assigned to: lennart
Priority: highest Milestone:
Component: daemon Severity: blocker
Keywords: Cc: ipse

Description

I don't know what causes it, but I'll be talking to friends/coworkers over pidgin (which presumably must use the esd interface??) and randomly when I receive an IM, I get no sound and pidgin locks up.

at this point, one of 2 things happens:

1. restarting pidgin works, but I no longer get any sound events

or

2. I can't launch any gnome programs anymore (nor firefox). trying to log out also hangs. init 3; init 5 doesn't even work - I get a hang as gdm auto-logs me in (I have my system configured for auto-login)

Attachments

I think I have the same problem. I usually notice PA being hanged when I'm not getting any sounds out of my VirtualBox? VM (which use PA as an audio source/sink on host). This happens on regular basis, so I can provide any information needed to debug this.

For the start, I'm using Ubuntu 8.04 Hardy Heron on x86_64 with pulseaudio 0.9.10-1ubuntu1 package installed.

I attached output of 'thread apply all bt' command in gdb when PA is hanged. Hope it will give initial information for debug. Also note, in this state PA does not respond to SIGTERM and can be killed only with SIGKILL.

This hang happens again and again, two-three times per day! It is very annoying to find a lot of events in my VM which I didn't heard about, because PA've hanged (again!). Please, do something with this. I would be glad assist debugging this.

I found that PA is very unstable, have horrible audio quality (clicks and audio distortion probably because of resampling) and introduce huge latency. I can't believe it was set as default for many Linux distributions. Probably this is due to misconfiguration, but *must* work out of box, isn't it?

Is this what you are experiencing?

For me - no. Memory usage does not increase.
