ALSA sound gone after sleep on 2.6.12

[Wolfgang Pfeiffer <roto@gmx.net>]

Hi all


Titanium IV, on 2.6.12 here, alsa-source 1.0.9b-4 compiled for 2.6.12,
pbbuttonsd 0.7.1-1.

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
/etc/init.d/alsa force-reload

I suspect a pbbuttons problem, but I'm not sure ...

pbbuttonsd.conf:

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

Regards
Wolfgang
