I noticed quite a few commits lately related to USB audio, and I was wondering what the current state is with its functionality.
I tried hrev45975 last night on my Thinkpad E420, but my USB DAC/amp wasn't functional. It shows up with listusb, but there's nothing in media preferences other than HDA audio, which doesn't work on this laptop. Is there anything in particular I need to do to get USB audio working?
Cheers, and thanks to all the developers for the ongoing hard work.
