Do you have your .asoundrc configured?  I use the one directly off the 
alsa site at 
http://www.alsa-project.org/alsa-doc/doc-php/template.php3?company=Midiman&card=USB+Audio+Quattro&chip=Cypress+AN2131XX&module=usb-audio 

(see bottom of the page.)  If you have that, then you can do:

      pd -alsadev quattro

...and not worry about actual hw: names.  This should give you all four 
channels by default.



A question as well:

Does anyone else with a quattro get a lot of noise on the input lines in 
PD?  I get all sorts of noise on input that sounds for all the world 
like I'm getting an 8-bit stream from the ins.  Any ideas?
