I had the same issue - post number 14 here fixed it, commenting out the lines like he said:
I've opened /etc/pulse/default.pa and commented 4 lines. Before: ### Automatically load driver modules depending on the hardware available .ifexists module-udev-detect.so load-module module-udev-detect .else ### Alternatively use the static hardware detection module (for systems that ### lack udev support) load-module module-detect .endif After: ### Automatically load driver modules depending on the hardware available #.ifexists module-udev-detect.so #load-module module-udev-detect #.else ### Alternatively use the static hardware detection module (for systems that ### lack udev support) load-module module-detect #.endif -- [Karmic] processes holding /dev/dsp* or /dev/snd/pcm* cause "pulseaudio: card not found - Null Output / Dummy Output" https://bugs.launchpad.net/bugs/394500 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
