[linux-audio-user] USB Quattro and Jack questions

[Denis de Leeuw Duarte]

Hi folks,

I've got a few questions about the USB Quattro and Jack. Hope you can anwer 
s ome of them:

I'm writing this app and I managed to get my Quattro going with Jack, but 
only two of the outputs are available as ports at a time (quattro1 or 
quattro2). Is there a way to invoke jackd so all four ins and outs are 
available as Jack ports? I use the .asoundrc file Patrik Shirkey wrote, but 
I understand too little of it to work it out :).

Another question:

How good/bad are the latencies other Quattro owners have experienced with 
Jack at 96k? Is it good enough to attempt close to real time signal 
processing in software? I've read somewhere that it is possible to bring 
latencies down to (quote) <0.5 milliseconds on a P500. Is this also possible 
with Jack? At 96k? I have an athlon-xp 1600 btw.

Regards,

Denis
