USB-Audio: Motu M4: no duplex profile

[GitHub issues - opened]

alsa-project/alsa-ucm-conf issue #214 was opened from pisquaredover6:

I have compiled alsa-ucm-conf v1.2.7.2 with the patches [3a6acaa5090a0c5a0d29c8a4906b6a60378774e2](https://github.com/alsa-project/alsa-ucm-conf/commit/3a6acaa5090a0c5a0d29c8a4906b6a60378774e2) and [ad1618cdd33f5c78ee1a0a9d3db362ffcb9f2596](https://github.com/alsa-project/alsa-ucm-conf/commit/ad1618cdd33f5c78ee1a0a9d3db362ffcb9f2596). With this, I have simplex audio, but no duplex profiles any more.

Is there any chance we can add a duplex profile, as it used to be the case before alsa-ucm-conf introduced the M4?
