I've found an mainline patch that hasn't made its way into the stable kernels and that may fix the issue (without reverting the commit mentioned in comment #37).
Would you be able to test the new kernel I've uploaded in: http://people.canonical.com/~henrix/lp1013183/ Basically, it contains the Precise kernel plus commit bfc89dec97a3db0f14393a86b2fc3d8e13b33c86 ("ALSA: hda/idt - Clean up power-map check code"). Could you also attach the kernel log for this kernel? (You can get the kernel log in /var/log/dmesg after booting the kernel) Thanks! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1013183 Title: Sound playback stopped working in 3.2.0-25 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1013183/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
