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].
