I'm not really new to either linux (4 -5 years) or

years) BUT I am new to getting more than one sound card to function at
the same time. I'm trying to get a linux based sound system (recording
only) up and running for our church. They currently have an 8 channel
mixer/amp and I would like to record8 analog channels in real-time. It
seems everything I have tried doen't work.
Here's the situation: I have alsa v 1.07 drivers, etc installed on a
2.4.25 kernel with the low-latency patch I have downloaded Jack v 0.99
and installed it. In conjunction with Ardour I can get either, BUT NOT
BOTH sound cards to record/play.
Short summary from the various mails on this list and from alsa-project.org:
It is possible via an .asoundrc but you wont get it to work with jack without
xruns. xruns are when one soundcard needs its new data (for playback) before
the other card. It happens because your soundcards won't run with _exactly_
the same frequency altough all clame to to 44.1kHz/48kHz.
There was a thread here (or on linux-audio-developer@?) where one disconnected
the quartzes from the second and third soundcard and connected them with the
one from the first soundcard. Another approach is syncing the cards via an
external digital sound signal (not timecode)...
Any ideas? I have even explored the 8 channel sound
cards but I just
know the church can't afford $500.
I know your poblem, I just ordered for 400EUR for our church and had to ask
the elder for permission...
God bless you,
Arnold
