Thank you for reporting this bug to Ubuntu. Ubuntu 10.10 (maverick) reached end-of-life on April 10, 2012. See this document for currently supported Ubuntu releases: https://wiki.ubuntu.com/Releases Please upgrade to the latest version and re-test. ** Changed in: pulseaudio (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/636901 Title: (On usb card removed) pulseaudio process goes to 100% CPU and cannot be restarted To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/636901/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 636901] Re: (On usb card removed) pulseaudio process goes to 100% CPU and cannot be restarted
This problem is still very much alive and well. I now use a script alias to ease the pain: alias snd='killall pulseaudio; killall gnome-volume-control-applet; pulseaudio -D; nohup gnome-volume-control-applet > /tmp/gnome- volume.log 2> /dev/null &' pulseaudio goes to 100% on one cpu at every resume, providing I don't unplug the USB soundcard and run the above alias prior to suspending. After this, and after resuming, plugging the device is not shown by Gnome Sound Preferences, but I can leave it open (on the Output tab), run the above alias, and watch it appear.

As far as I remember, yes. I used ctrl+c while in gdb to get to the prompt. But I'm pretty sure that it was still @ 100% CPU. -- (On usb card removed) pulseaudio process goes to 100% CPU and cannot be restarted https://bugs.launchpad.net/bugs/636901 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Sad to hear that. Also, was pulseaudio running on 100% CPU when the backtrace was taken? It looked like all threads were in a waiting state. -- (On usb card removed) pulseaudio process goes to 100% CPU and cannot be restarted https://bugs.launchpad.net/bugs/636901 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

While debugging #11, I found that if I didn't have the card plugged in first then it would never be recognised. The only way that it would randomly be recognised is if I started PA, plugged in the card, then started gnome-volume-control-applet. When the card wasn't "found", the following was produced in the debugger: (gdb) run Starting program: /usr/bin/pulseaudio [Thread debugging using libthread_db enabled] process 3652 is executing new program: /usr/bin/pulseaudio [Thread debugging using libthread_db enabled] W: pid.c: Stale PID file, overwriting.

[Bug 636901] Re: (On usb card removed) pulseaudio process goes to 100% CPU and cannot be restarted
There are so many regressions here it is getting very hard to test this. The sound card is now only being recognised by the system randomly -- it was 100% earlier. This would be okay if restarting PA (and gnome-volume- control-applet, which appears to be far, far too tightly coupled to PA) fixed things, but that is equally hit and miss. I'd wager it's timing issues in bad code, probably in gnome-volume-control-applet, but that's not for me to determine. Note that after starting PA, I then start gnome-volume-control-applet before proceeding. See next note.
