Looking at the latest logs, I think we actually have two different bugs to deal with.
One being the long system delays, which might or might not be related to the graphics driver. The other one being the audio driver. The regular underruns at 194 ms, and the high interrupt count, both seem to indicate some problem with the controller. -- 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
