So you removed the connection 7 seconds after, I assume, then waited 20-30 seconds, then killed pulseaudio.
( 7.587| 7.586) D: module-udev-detect.c: /dev/snd/controlC2 is accessible: no This probably indicates either a problem in alsa-lib when closing the connection, or PA struggling with detecting the sound card having been removed. I'll need a backtrace to nail this bug down further. If you have the time, can you follow the instructions here: https://wiki.ubuntu.com/Backtrace For point 4 at that instruction, wait till PA eats 100% CPU, then press Ctrl-C. ** Summary changed: - pulseaudio process goes to 100% CPU and cannot be restarted + (On usb card removed) pulseaudio process goes to 100% CPU and cannot be restarted -- (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
