Jack can't configure capture channel (or playback), in fact Jack
doesn't work at all with that device. It says it can't set the hardware
sample formats. This is also a problem with Alsa, using hw:num.

The device works on playback through alsa plughw and OSS
emulation. But when trying
to get input from plughw:num, nothing happens (no sound).

It's very fishy.
