Well, I just got a Quattro today (ebay rules :) ) and plugged it in.
Finally I managed to get two channels out of it (in and out) but 
whatever I do I can't get it to 4.

Is PlanetCCRMA kernel a must? For some reason my FC6 decided to use 
non-realtime stock FC kernels but I don't remember doing anything 
related to that.

Done that.

I appear to not to have this! I wonder where it dissapeared to. OTOH, 
Jack appears to work fine with alsa.

I tried this. I set it to playback only and set it to 4 channels. Jack 
wouldn't start up. OTOH, I'm not sure it is picking up my new .asoundrc 
file since I can't see the q4 interface in the drop-down list, I can 
only see hw:1, hw:1,0 and hw:1,1.

Any ideas, anyone?
