Hi all,
I'm trying to get a motu 828 mkii working on lenny-amd64
I can't get it to run reliably at latencies lower than 8ms; setting
qjackctl about 5ms, the procces shows xruns/is killed by the watchdog;
setting it at 4 ms, it does not start.
At 8 ms, it seems to work, not tested under load.
kernel is 2.6.24-1
qjackctl is 0.3.2
libffado 1.999.14-876
jackd version 0.109.2 tmpdir /tmp protocol 22
put your tmpdir on a shared memory
filesystem (/dev/shm)
Any hints about it?
Use realtime priority and a RT patched kernel.
Note that FFADO isn't supposed to work at very low latencies at the
moment. I'd say 3x128 (=8ms) is about the limit of the current version.
Will be better on the long run, but at the moment that's it.
Greets,
