Have you tried unloading the snd-usb-audio module and the reloading it with implicit_fb=1 as in "modprobe -r snd-usb-audio" and "modprobe snd-usb-audio implicit_fb=1" ? If not, try it. If it works and your playback issues are gone then your device may just need a quirk. If it doesn't work we still have dyndbg to go through. Last but not least, please use a vanilla kernel for these tests. Thank you, Geraldo Nascimento
