Bug Description
Binary package hint: linux-image-
After upgrading the gutsy kernel from linux-image-
Playback with headphones is also far to quiet, so even with completely raised levels of the master and PCM mixer controls I get only very low output. This probably means that the automatic amplification for headphone output is not working.

Maybe the output of lsmod could also be of help.
