Comment 0 for bug 923409

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:
