We should also test some of the 3.8 release candidates to know which exact one introduced the regression. Once we know that, we can start the bisect.
Can you test the following kernels and post back? We are looking for the first kernel version that exhibits this bug: v3.8-rc4: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.8-rc4-raring/ If v3.8-rc4 does not exhibit the bug then test v3.8-rc6: v3.8-rc6: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.8-rc6-raring/ If v3.8-rc4 does exhibit the bug then test v3.8-rc2: v3.8-rc2: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.8-rc2-raring/ Thanks in advance! -- 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: [INTEL DP55WG,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
