dear list members,
I have a question on using zita-bridge with jack2, obviously I'm
missing some detail (?).
I'm trying to get two usb soundcards working as inputs for recording.
as usual, I start jackd via qjackctl with one of them, say, the
soundcraft notepad12fx as hw-device (with -r 48000 -p 512 -n 2).
now, I want to add the 2nd interface, my zoom h4. in a terminal I put
#zita-a2j -d hw:H4 -r 48000 -p 512 -n 2
I get
#Starting synchronisation.
and I can see the zita-bridge both in the graph window of qjackctl and
in my daw (reaper).
the problem is that I don't get any signal from the device connected by
the zita-bridge. I have also tried to change both devices - without
success. furthermore, I've tried to leave some of the parameters (-p
and -n) out.
am I missing something?
thank you very much for any suggestion!
have a good day!

does the # mean you are running things as root? Jack and zita should only
ever be run as a regular user and never as root/system.

By no signal you mean there is a mic on the input but the audio does not
show up? (The meters on the device itself show level?)
Does the signal ever show up on each device A) when not running jack? B)
as the sole jack master?
Is the device you are using as jack master also the device you are using
for monitoring? (output to speakers/heagphones?)

yes, by now, the master device is, as usual, the monitoring device. for
the moment I'm just focussing on the inputs.

hi,
still concerned with the issue that zita-a2j doesn't work properly on
my computers (I’ve also tried it with another machine, both run arch
linux) I enabled zita-a2j in verbose mode which tells me:
playback : not enabled
capture :
nchan : 2
fsamp : 48000
fsize : 256
nfrag : 2
format : S16_LE
whilst "playback" is indicated to be disabled, "capture" lacks a
state,
at all.
could this be a useful hint for solving the problem?
I have uninstalled zita-ajbridge, restartet and reinstalled, but the
problem persists.
by the way, I tried also if playback works (zita-j2a), but in the same
manner it doesn't, i. e. zita-j2a shows up in jack’s graph and in the
daw, but there is no signal.
thanks in advance for any suggestion.

What do you mean by 'lacks a state' ?
Is there any output after the lines you quoted, like

playback : not enabled
capture :
nchan : 2
fsamp : 48000

-0.114 1.000094 327
0.128 1.000019 328
etc. ?
This problem is quite mysterious...
I've got zita-j2a running on one of my machines at work, with
a Digico 48-ch MADI interface for two months or so without
interruption. Use it almost every day, no problems...
I have uninstalled zita-ajbridge, restartet and
reinstalled, but the
problem persists.
Could you try jaaa -A or japa -A with the same sound card and
see if you get any signal in or out ?

no, on both my computers there’s nothing printed after "Starting

I tried japa with that soundcard (Zoom H4n with usb connection):
[christoph@x270 ~]$ japa -A -d hw:1
playback :
nchan : 2
fsamp : 48000
fsize : 1024
nfrag : 2
format : S16_LE
capture :
nchan : 2
fsamp : 48000
fsize : 1024
nfrag : 2
format : S16_LE
synced
Connected to ALSA with 2 inputs and 2 outputs
from the speaker of the device I can hear constant noise and its meters
show constant input at around -10 db. in the little window which is
opened I can also see some movements in the diagram when I gently tap
the device’s microphones. so, yes: there’s plenty of signal.
Maybe it’s related to my distribution, arch? I have no clue.
in alsamixer there’s nothing to adjust for the H4n, it says: this
device has no controls.
so, indeed mysterious.
I have uninstalled zita-ajbridge, restartet and
reinstalled, but
the
problem persists.

ciao & thanks & have a good day!
