Titanium IV, on 2.6.12 here, alsa-source 1.0.9b-4 compiled for 2.6.12,
After resuming the system from sleep sound's gone.
In some cases a
kill -HUP `cat /var/run/pbbuttonsd.pid`
is enough to get sound back.
Often a complete reload of alsa is neccessary to get sound
back. Something like
I suspect a pbbuttons problem, but I'm not sure ...

Any mistakes in that file above?
Or do I need a special file/script somewhere to restart alsa after
sleep? IIRC all this wasn't a problem some weeks/months ago ...
Thanks in anticipation
