Thanks for testing!
Thanks for *your* help on *my* problem!!!
I attached a patch below, only compile-tested. Please also check the USB ID again, as I'm not sure whether you sent the right lsusb dump (the device name looks suspicious).
Yes, it's been the right lsusb dump. The reported device name is a bit strange indeed. In /proc/asound it is listed as F8R which is is a bit more reasonable.
If that doesn't work, try debugging the value returned by urb.c:snd_usb_audio_next_packet_size(). For your device, you should end up in the "subs->stream->implicit_feedback" branch.
I've tested your patch. Unfortunately I don't get any sound. snd_usb_audio_next_packet_size() returns from the "subs->stream->implicit_feedback" branch. But the return value is always 0. ('frames' is returned, not the 0 from the if (WARN_ONCE...) statement).
Any ideas how to proceed?
Thank you very much again,
Felix
