That patch indeed fixes the problem and
zita-j2a works like a charm now. Nice :) And as expected it uses less
CPU than alsa_in and alsa_out.
I tried alsa_loopback from zita-alsa-pcmi this morning (as
"./alsa_loopback hw:1 hw:1 48000 2048 10"). No errors, no crashes, but
no output on the soundcard. Last line printed is "synced". However, the
documentation is sparse so I didn't know what all these parameters are
for and guessed most of them.
The ajbridge has the same problem. There's the quality-parameter that
defaults to "48" but that's all I get to know about it. No value range,
no indication whether 0 is better or worse than 1000. You could add some
hints to the readme ;)
But thanks for all your work you contribute to linux-audio and your
support :)
Jannis
