1. With the low-latency kernel, jack
dropouts/underruns are a problem
when jack is configured to bridge to pulseaudio. Without a pulseaudio
bridge, the dropout are nonexistent.
I'd suggest to get rid of pulseaudio. It doesn't do anything useful
for an application like yours.
2. I have a similar issue with zita-a2j and zita-j2a
with lost of
dropouts on the ALAS side, even though the jack side shows no overruns.
How does this show up (i.e. how do you know it is the ALSA side) ?
What do you get with the -v option ?
Can extra buffering be applied to the zita programs?
Maybe that is
what the -n option is for?
Using more periods could hide the problem, but it's never a real
solution.
Are you sure things are running with real-time scheduling ?
This requires some configuration in /etc/security/limits.conf,
as well as for Jack itself.
Why do you need zita-a2j/j2a anyway ? Using a single multichannel
card is usually the better solution.
