This device reports that it supports two channels. What makes you think that you can play eight channels?
amixer: Control hw:2 element read error: Invalid argument usb 1-1.3: 10:0: cannot get min/max values for control 3 (id 10) usb 1-1.3: 2:1: cannot get freq at ep 0x1
These are bugs in the device firmware. However, the driver could handle them better.
