alsa_in/out work fine with alsa dmix/dsnoop devices. zita-a2j does not.

I am using a alsa-loopback device (for non JACK apps such as Flash..)
and alsa_in/out to connect the alsa-loopback to jack. The .asoundrc (in
use is the one from
http://alsa.opensrc.org/Jack_and_Loopback_device_as_Alsa-to-Jack_bridge#asoundrc_definition

# zita-a2j -dcloop
Can't open ALSA capture device '-dcloop'.

# alsa_in -dcloop
selected sample format: 16bit
delay = 7626
..

works OK.

The other way' round starts fine, but there's no signal coming though.
# zita-j2a -dploop
Starting synchronisation.
Detected excessive timing errors, waiting 15 seconds.
This may happen with current Jack1 after freewheeling.

[It's jack2 and no freewheeling at all.]

# alsa_out -dploop
works as expected.

best,
robin

PS. NTL I've created man-pages (based on the README) and packaged it for
debian: http://rg42.org/gitweb/?p=zita-ajbridge
