An example could be -n3 -p128 -r4800 which would result in a JACK latency of 256/4800*3=8ms. I do think the onboard audio interface should work properly too, how did you measure its latency? I've successfully got system latency below 10ms with the same codec on a Cubieboard so it should be possible on the Banana Pi too. Jeremy
