Virtual 48 ch card using 2xDigi9652 & jackd
 
|
Dear all,
a few questions: - is anybody out there using 3 RME DIGI9652 simultaneously with 3 named jack servers. I do that and have severe stability problems , i.e. after a few hours one of the jack servers does not deliver anymore samples to my app. It seems to be an alsa driver problem since aplay also cannot contact the "crashed" soundcard. However I suspect that jackd is somehow causing that behaviour ??? Anybody having this problems too ? - I try to build a virtual 48 ch card out of my 2 RMEs using the asound.conf below. What happens is that jackd -v -d alsa -d ttable reports 52 I/O channels (not 48 as i would expect from ttable definition). So far so good. But when my app (requesting for 48 ports) connects to jackd, jackd registers only 24 connections and my app crashes. Any ideas ?

They have to be synced via an spdif cable or they will drift (or internal word clock). I think it's probably worth calling this an Alsa problem and going over to the alsa list for more help. Once it works fine as a normal 48 channel soundcard *then* try and make it work with Jack Ed W ------------------------------------------------------- SF.Net email is Sponsored by the Better Software Conference & EXPO September 19-22, 2005 * San Francisco, CA * Development Lifecycle Practices Agile & Plan-Driven Development * Managing Projects & Teams * Testing & QA Security * Process Improvement & Measurement * http://www.sqe.com/bsce5sf _______________________________________________ Jackit-devel mailing list [hidden email] https://lists.sourceforge.net/lists/listinfo/jackit-devel |
