You might want to try to check the frames' status in retire_playback_urb(),
I've looked that function over, but it's not clear where in the various structures I'd find the status.
Copy that code from retire_capture_urb().
if the data is put on the USB bus, but the receiving device (my audio card) loses it, there's no way the above will show this?
Isochronous packets have no error handling or reporting, except for the CRC. You will see an error report only if it happend before the packet was put on the bus. (Which appears to be the case for you.)
