Public bug reported: Since the update of the kernel (version 3.2.0-11 and 3.2.0-12) sound does not work anymore (probably due to the alsa-related changes made in 3.2.0-11 https://launchpad.net/ubuntu/precise/+source/linux/3.2.0-11.19)
The output of "cat /proc/asound/pcm" is empty (the soundcard is listed properly there with kernel prior to 3.2.0-11). The drivers are loaded, though: 00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 02) Subsystem: Hewlett-Packard Company Device 2a5d Flags: bus master, fast devsel, latency 0, IRQ 43 Memory at f9ef8000 (64-bit, non-prefetchable) [size=16K] Capabilities: <access denied> Kernel driver in use: snd_hda_intel Kernel modules: snd-hda-intel ** Affects: linux (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/923409 Title: No sound To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/923409/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
