Hi all!
I just got a USB tape dec, which acts as an ALSA USB-audio interface. Now I
wonder can I run both my PCI soundcard and the tape dec with one JACK, so I
can use the deck to playback (digitalise tapes) and record? I'd also like to
be able to listen live to tapes playing through the tapedeck, so just connect
tape-output to soundcard playback.
Kindest regards
Julien

Hello Julien,
jack diplomat will be your friend.

Ah, Julien, please. You of all people subscribed here should know about the
answers you will get:
- No, its not possible. The soundcards sampling clocks have to be synced. And
as long as we are not talking firewire or connecting the devices via
spdif/word-clock, the only "solution" would be to solder a connection from the
first soundcards crystal to the second soundcard. Which is impossible with two
different devices probably using different crystal frequencies.
- The only way this can work is by using a jitter-buffer doing live-resampling
to work around the clock differences. And this doesn't sound good nor will it
give you low-latency (the bigger the buffer, the better the result).
And all this was explained numerous times on this list and on lad :-)
Have a nice week,
Arnold

Hello Arnold!
Well I heard, that people sometimes did some highly dark and magical
experiments. Now Conrad told me of Jack diplomat, which unfortunitely I can't
find. Seems to have gone off-line. Anyway I don't need low-latency between the
two. I just need some kind of connection so I can listen, nothing fancy and
musically relevant. Simple entertainment. :-)
Does anyone know, where I can get jack-diplomat?
Kindest regards
Julien

Hi Julien,
in this case you might try alsa_in and alsa_out with -d plughw:1, it won't give you
low latency either, but it's worth a trial. Each alsa_in/out will produce a jack
client you can route to or from.
Regards
Frank

Thanks! It seems to work. Maybe Ishould get JACKD 0.116.3 or later, to get it
started more easily. Besides that, fine!

If you want to use both cards in the same jack graph, you
will inevitably need to compensate the timing difference
with resampling. Both Jack diplomat and Pulseaudio are able
to do it, so it's not so big problem in this case.

I did manage to get the jack diplomat source here:
http://spark.woaf.net/jack_diplomat-0.70.tar.bz2
I'll have to wait till I get home tonight to see if this will work out
but from glancing through the README, I've got my hopes up again.

Hi!
I just found the easiest way there is and it's quite stable, good in quality
and it was already there. I used ecasound:
ecasound -f:16,2,48000 -c -i alsahw,2,0,0 -o jack,system
Well, well... (beating myself with rubber bats around the head! :-) )
Kindest regards

A bit OT, but I'm using alsa_in alsa_out with on a netjack slave machine
which soudncard is a POD XT Pro, and I can get it working with low
latency, without any problem.
