I also tried loading the speakup_soft module and running espeak. No error messages appear. Nothing abnormal in the syslog either. That's why I think sound is muted.
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...
Please be aware that this is iso only supports 64bit cpus.
What I really need is a command for unmuting a sound card. I don't know how to do that at the command line. I guess that's technically a linux question, not a grml question.
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%
