I installed an update after being offline for 3 weeks. My machine is
a Thinkpad t61p and after the update sound does not work. kmix will
not start and kde complains that the sound devices are not available.
The sound driver (snd_hda_intel) is loaded as are the other usual
suspects.
Has anyone else had a similar problem?

More information:
I rebooted and noticed a popup dialog from arts:
Informational - artsmessage
Sound server informational message:
Error while initializing the sound driver:
device /dev/dsp can't be opened (Permission denied)
The sound server will continue, using the null output device.
I checked /dev/dsp /dev/mixer etc:
crw-rw---- 1 root root 14, 3 2009-09-14 09:51 /dev/dsp
crw-rw---- 1 root root 14, 0 2009-09-14 09:51 /dev/mixer
It doesn't help to change the permissions cause they get reset at boot
time. Most devices are owned exclusively by the system anyway.
