I'm having trouble getting implicit feedback working with my custom
capture/playback USB audio class device, even with the latest kernel
(3.6.6). I presume it's a problem with my device's configuration, but
can't figure out exactly what the problem is (after a whole lotta
Specifically, my device captures an AES/EBU data stream (at a frame
rate dictated by the source device), sends it to the computer via USB
and ALSA, and then takes a processed audio stream from the computer
via ALSA and USB, and sends it out at the same clock rate. The output
stream should have the exact same frame rate as the input stream,
governed by implicit feedback.
Is there any commercial USB hardware out there that supports implicit
feedback? I assume the ALSA developers are testing against something,
but I can't find anything appropriate.
Or, is there source available that runs on some USB-capable micro
board that supports it?
