With the patch applied, could you please plug out the device, do a "sudo dmesg -c", then plug it back in and run "sudo dmesg -c" again, and send us the output. Also, I'd need to see the contents of /proc/asound/card1/stream0 again, to prove that the patch does the right thing. > I use aplay -D hw:1,0 to run the tests (bypassing pulse etc) Given that you seem to have access to an USB analyzer, can you look at the packets and see if there's anything wrong with them? And please also compare the setup sequence again, in comparison to what the Windows driver does.
