so i just rebooted and only plugged in my usb dac after the system had started... i plugged the usb dac in loaded amarok, and it worked perfectly :/
as expected it displays as device "1" from sndstat and aplay -l
strange... i don't know what causes it to sometimes not work, but it seems exactly like the OP's problem. I'll post back details from sndstat aplay -l etc if it stops working again
this is wierd...
