Per comment #63, this bug does not exist in v3.9 final. We now also know v3.10 final has the bug. That would indicate this bug was introduced in one of the v3.9 release candidates.
In comment #58 you mentined that you tested v3.9-rc1, but were unable to test due to issues with the desktop, so we should try some other release candidates. Can you test v3.9-rc4: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.9-rc4-raring/ -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1201528 Title: [Realtek ALC889] - Audio Playback Unavailable To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1201528/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
