No difference after installing linux-backports-modules-alsa-karmic (I presume you meant linux-backports-modules-alsa-karmic-generic and linux- backports-modules-alsa-2.6.31-14-generic as the indicated package can't be found).
I had to remove my usb sound device to test things well and restoring back to the "post install" configuration I noticed that, although indicating to use the internal sound device in the sound preferences, sound actually gets routed through the now reattached usb sound device. Looks like thing are getting a bit confused in/over there. -- PC Speaker can not be switched off in sound preferences https://bugs.launchpad.net/bugs/465092 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
