Had similar problems on 32-bit version of Karmic. As advised in several places, get rid of Pulse-audio (sadly) en switch (back) to Alsa:
sudo apt-get remove pulseaudio sudo apt-get install esound # be sure to check any muting of channels, can be done in graphic mixer, or commandline version: alsa-mixer If this does not fix your problem, you can easily get pulse back using the reverse commands. -- Karmic doesnot shutdown or restart || Intel D101GGC, ATI X200 integerated Card https://bugs.launchpad.net/bugs/482694 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
