alsa-project/alsa-ucm-conf issue #415 was opened from beatboxa:
The newest [Motu 828 (28x32)](https://motu.com/en-us/products/828/) does not appear to have a UCM yet. It is a class compliant USB device; so as a result, it generally "works" at a very basic level; but default channel mappings and profiles do not.
The system appears to default to only 2 channels in and 2 channels out. So, for example, surround playback seems to mix into either the left or right channel.
In qpwgraph, it shows 30 inputs (I believe this includes an additional 2-channel loopback at the end) and 32 outputs, all marked as "AUX#," where # starts with 0. I was able to identify which AUX# corresponds to which input or output on the device, through the use of qpwgraph and the device's built-in digital VU meter.
I have tried to create a UCM or even an asoundrc; but I have no idea what I'm doing. The documentation and examples are not intuitive for me.
Could I collaborate with someone in order to get this audio interface supported? I'd be happy to run any commands and tests you advise on.
