[LAU] Sending audio out and back into JACK

[Andrew C]

Thanks for the information guys, didn't know that a multiple in/out
audio interface creates _1 system_in/out ports in JACK.

That makes a lot of sense and is quite cool, I'll definitely have to try it out!

Ouch, I knew there was a catch! This means that the incoming audio is
delayed by the latency or 2x?
JACK is running at 10.2ms latency currently, but if I send it out and
then back in, it's delayed by 10.2ms or 20.4ms?

Thanks guys for the info!

Andrew.
