Thanks for your reply,

I am not particularly trying to use Jack, but is there another way to
get real-time output on OS X? What driver name should I give to the -o
flag if not jack?

I tried your suggestion 'ecasound -i somefile.mp3 -o jack' and it
seems like it's working, but no audio. I opened up JackPilot Routing
on OS X and I can see that ecasound is registered during the
performance. But when the performance ends it disappears, which I
suspect is expected behaviour. Problem is that ecasound is not
automatically patched into my system's output by Jack, is there a way
to auto-enable this (I cannot do it manually as ecasound is only
listed in jack router when half-way through performance)? I'm sure
there is a simple explanation and I'm being really stupid :-)

Thanks

Peiman
