It is indeed. I just commited a change to grml-autoconfig which should
take care of this issue.

To test the fix (works for me) you can use this iso
http://jenkins.grml.org/job/grml-full-amd64/774/artifact/2011-12-16_11-03-41/grml_isos/autobuild_2011-12-16_11-03-41.iso

Please be aware that this is iso only supports 64bit cpus.

You can get a list of mixer controls via:
amixer scontrol

To unmute a specific channel (in this example i unmute master):
amixer set Master unmute

To set the volume to 75% on PCM:
amixer set PCM 75%
