Hmm - there could be some interaction with the audio
buffer and its low/high water marks. The writing should adapt
to the audio speed instead of using a fixed blocksize and
timer interval. I don't have a good idea how to do that
without changing the code structure.
Does it help to use larger blocks, eg "digital 10"
or "digital 20"? (At about 30 a limitation of the
VM system is hit - raw SCSI commands cannot exceed
MAXPHYS=64k bytes.)
Does it have a positive effect for you to remove
the sched_yield() call in sig_timer(). I don't think
that makes much sense.

Yes, but be should do some finetuning before.

best regards
