[PATCH 0/4] ALSA: usb: UAC3 new features.

From: Jorge Sanjuan
Date: Fri Apr 20 2018 - 13:03:48 EST

Now that the UAC3 patch [1] has made it to linux-next I have some extra
features to make a UAC3 device fully work in Linux. Including Jack
insertion control that I have put on top of this other patch [2] for
UAC2. Also adding support for the UAC3 Mixer Unit which is most likely
to appear in most headset type devices.

UAC3 devices also require to have a Basic Audio Device (BADD) in a separate
config for which both Ruslan Bilovol and myself have submited different
approaches[3][4] but I don't know what the final merge will be. Once there
is official support for BADD, we'll need to test it with an actual UAC3
device to confirm it all wokrs.

All this features are tested with an actual UAC3 device that is still in
development. For this patch series, only the legacy config (#1. UAC1/UAC2)
and the UAC3 config have been tested. The BADD config is only tested using
and updated verison of [4].
