When I use -istdin and -odac, with a microphone
attached to stdin, I hear the mic sounds processed
by csound, but delayed, even with small -b and -B.

As time progresses (5-15 seconds and beyond) the
delay grows larger and larger quickly becomimg 10
seconds in length and still growing.

The input and output is happening on the same 
physical sound card.  I suppose if the card used
two different crystals for timing input and output
then the effect could be explained right?

Anyone have this type of real-time dsp working?
