Not sure, if this may relate to your problem, but ..
I use xine plugin and every once in a while I had a short interruption of
sound. Today I was tail-ing -f syslog for another reason and there was this
little glitch again! Just a very short interruption with no sound. I spent
several weekends to find out, why xine always tells me, that "fixing sound
card drift". I was p***ed by my hardware, but now I found out, what cause
the problem. It's my ntpd, that steps the clock on my VDR hardware. To fix
this, I now start ntpd with the "-x" option.
For Reference from man ntpd:
-x Ordinarily, if the time is to be adjusted more than 128 ms, it
is stepped, not gradually slewed. This option forces the
time
to be slewed in all cases.
Regards,
Martin

The only way i know how to fix that is to run your FF card with some kind of
software playback (ie; xine). I wish we had a version of firmware that
didn't
have this problem.. or at least a way for it to recover itself.
