Hmm ... I could try and open the three raw devices

see how that will work out, if they perhaps are drifting?
Tomorrow! :)
/j
.. which I have done now:
a) One program 'capture' opens two devices ("hw:0,0,0" and
"hw:0,0,1")
and merges them into a single stereo image which is piped out on stdout.
b) another program 'playback' opens a third device ("hw:0,0") for
output
and reads a stereo image from the pipe on stdin
used as: ./capture|./playback
.. and works without flaws
What does NOT work - and what might be a hint to what is wrong - is
starting jackd as either playback- or capture only (with -P or -C). Only
the duplex mode -D is running stable.
I don't get this? :-/
