Seconded - same issue for me, inconsistent detection of sound card. AMD64, Realtek ALC883 card, Ubuntu 10.04 upgraded thru Update Manager yesterday.
Also, not sure if this is relevant but I can predict when there will be problems as the volume mixer fails to appear in the Panel on boot..... killall pulseaudio and then alsa force-reload works every time. The only thing I've changed from the auto updates in the upgrade was - remove "wins" from nsswitch.conf, as a fix to Rhythmbox crashing on launch; and - sudo ln -s compiz compiz.real which was a fix to all windows/apps having no display style or borders on boot Everything else is straight "out of the box" from update manager -- module-udev-detect races with module-default-device-restore https://bugs.launchpad.net/bugs/557421 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
