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 Desktop Packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/636901 Title: (On usb card removed) pulseaudio process goes to 100% CPU and cannot be restarted Status in pulseaudio package in Ubuntu: Incomplete Bug description: Binary package hint: pulseaudio Description: Ubuntu maverick (development branch) Release: 10.10 When I unplug my USB sound card, which works fine, the pulse audio process goes to 100% CPU (on one processor) and remains in that state. Attempts at a restart result in: $ pse pulse 2192 ? 00:00:42 pulseaudio $ sudo /etc/init.d/pulseaudio restart * PulseAudio configured for per-user sessions $ pse pulse 2192 ? 00:00:42 pulseaudio But the process is not really restarted. The only way to stop it is to kill it, but then it is not possible to start to process. marc@niff:~ $ pse pulse 2192 ? 00:00:42 pulseaudio marc@niff:~ $ kill 2192 marc@niff:~ $ pse pulse marc@niff:~ $ sudo /etc/init.d/pulseaudio restart * PulseAudio configured for per-user sessions marc@niff:~ $ pse pulse There are a few issues here: 1. The messages aren't useful, indeed they are inaccurate, and need to be improved 2. There is no log file in /var/log, so how does one debug? 3. The process shouldn't go to 100% CPU 4. It should be possible to force a process restart 5. It should be possible to start the process once killed. $ apt-cache policy pulseaudio pulseaudio: Installed: 1:0.9.22~git20100719-0ubuntu1~ppa2 Candidate: 1:0.9.22~git20100719-0ubuntu1~ppa2 Version table: *** 1:0.9.22~git20100719-0ubuntu1~ppa2 0 500 http://ppa.launchpad.net/ubuntu-audio-dev/ppa/ubuntu/ maverick/main i386 Packages 100 /var/lib/dpkg/status 1:0.9.22~0.9.21+stable-queue-32-g8478-0ubuntu17 0 500 http://gb.archive.ubuntu.com/ubuntu/ maverick/main i386 Packages To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/636901/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
