Thanks, David. linux-backports-modules-alsa-karmic does indeed fix the issue on my Macbook 3,1 running karmic. The backport also fixes headphone detection trouble, e.g. speakers are now reliably muted when something is plugged into the headphone jack.
This can probably be closed as fix committed though ALSA still tracks the issue as "new", presumably due to a lack of positive test reports. -- Subwoofer not working in Intel Macbooks https://bugs.launchpad.net/bugs/305750 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
