Thanks for testing, Natalia. So it sounds like this bug was introduced in a Sauce patch added in Raring. However, it also sounds like this is broken in the current mainline kernel, since you were able to reproduce the bug with 3.11-rc4.
It would be helpful if you could test some additional kernels. First the -proposed Raring kernel, just to confirm it wasn't fixed yet: https://launchpad.net/ubuntu/+source/linux/3.8.0-28.41 If it still exists in -proposed, we have two options, we can bisect the Raring kernels to find the commit that introduced the regrssion and/or we can bisect the current mainline kernel to find the commit that breaks it there. It may be the same patch that breaks audio in both instances. It might be best to find the commit that breaks this in mainline first, since it is going to affect Saucy and we can work with upstream to get it fixed before release. We can then see if that same patch was applied to Raring as a Sauce patch. Can you test the v3.11-rc1 kernel to see if the bug also exists there: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.11-rc1-saucy/ If 3.11-rc1 is good, can you test v3.11-rc2: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.11-rc2-saucy/ If 3.11-rc2 is good, we should next test v3.11-rc3: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.11-rc3-saucy/ Based on these tests, we should know the two 3.11 kernels we should bisect between. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1201528 Title: [Realtek ALC889] - Audio Playback Unavailable Status in “alsa-driver” package in Ubuntu: New Status in “linux” package in Ubuntu: Incomplete Status in “alsa-driver” source package in Raring: New Status in “linux” source package in Raring: Incomplete Status in “alsa-driver” source package in Saucy: New Status in “linux” source package in Saucy: Incomplete Bug description: This is a fresh upgrade to raring. During the weekend, I updated from precise to quantal, and from there to raring. I did not use sound while the system was in quantal, so no idea if the bug was present there as well. The symptom is: * after some period of sound usage, playback stops working What I mean with sound usage is: I tried having a meeting with: mumble, skype, and google hangout, and in all three cases, audio input/outout will work just fine for ~5 minutes, and the playback just dies (people tell me they keep listening to me, so mic works fine). The only way to solve this is by rebooting. After one of the reboots, I was able to play a 20 minute video with mplayer with no further issue. Then opened skype and after ~3-5 minute talk, audio playback died again.
