Thanks, mon2!
I assume you refer to the "USB Audio 2.0 Device Software - source code" entry in the "Software Section"
If I run the "app_usb_aud_xk_216_mc" application, I do get sound, but only 2 channels. Also the device is listed as "USB Audio 1.0"
How can I make use of all 8 channels?
Thank you,
Sukandar

Hi. Not an audio developer but believe you have to modify the defines and select the makefile to suit your project. See section 7 of the usb 2.0 audio design guide and also an1027 by xmos (Google will have the link).

thanks again mon2
I finally had time to work on this again

turns out, the easiest way to enable USB2 and more than 2 channels, is to select the appropriate build configuration...
the project provides quite a few different options
