Hi,

the Pioneer UAC1 devices still didn't work with the recent changes,
and after debugging sessions, a few issues were discovered.  Below are
the patches to cover those errors.

I have compiled and tested version 532a208ad610 (Avoid implicit feedback on Pioneer devices)

and can confirm that Pioneer DJ DJM-250MK2 works again (playback, recording – tested through JACK in duplex mode).

Thanks,

Franta
