:) 4 better than 2 ... :? but it's odd cause the MOX USB audio card has two modes:
- 2 audio channels
- 4 audio channels
The change of mode needs reboot the hardware. In fact, 2 channels is the only mode that works for me with the "native" Windows driver cause it sucks less. Look at this:

Thanks for the patch. This is my checking (2 audio channels mode):

So it looks theonly difference are the wMaxPacketSize value and this dmesg error:
[ .....] cannot submit datapipe for urb 0, error -28: not enough bandwidth
Summary: at the moment the patch doesn't work for me :( ... but I'm all ears ;)
Thanks again.
