Now I found something interesting about this bug. The bug seems to be purely an ubuntu introduced bug, because it i fixed with the current alsa. This bug was actually fixed in alsa around the 7th of March (bug report along with the patch is here: https://bugtrack.alsa-project.org /alsa-bug/view.php?id=3800 ). I have looked in the ubuntu packaged ALSA sources, and diffed them against a recent mercurial snapshot of alsa- driver (2008-05-02), and it seems that the patch has been incorported into the ubuntu packaged alsa sources already.
However the fix doesn't work for the ubuntu packaged alsa driver. It works great on my alsa snapshot though. So this bug has probably been introduced by ubuntu at some point, or there is something missing in the ubuntu that makes the upstream fix inefficient. The fix as described in alsa bug report was to add a new model for the ALC883 codec. The new model name is pi2515. Adding the line options snd-hda-intel model=fujitsu-pi2515 at the end of /etc/modprobe.d/alsa-base is supposed to fix the problem. It does fix the problem when alsa is manually compiled and installed, but doesn't fix it with the ubuntu packaged alsa driver. -- [Ubuntu 8.04alpha5] Notebook: headphones and speakers not muteable seperately https://bugs.launchpad.net/bugs/194866 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
