[linux-audio-user] Jack setup issue

[RachelAPP]

It's me again with some config issues..
After getting my soundcard (Terratec DMX 6 Fire) to work correctly with 
Audacity, i decided to use Muse... So i installed Jack.
But when i do jackd and it creates the alsa driver, it puts 0 and 0 for number 
of input and output channels. When i try to force it into something else with 
-i 6 and -o 2 for example, it tells me "ALSA:cannot set channel count to 6 
for capture".
Within Audacity, i can set the number of recording channels to whatever i want 
and they all record properly so i'm a bit surprised why it doesn't work with 
jackd... Any idea? Any help would be very much appreciated as i've been 
reading various FAQ/help pages on various sites but haven't found any answer 
yet...
