Would it be possible to add support for the Moon Neo 230HAD?

The output suggests it only supports PCM. There is only one altset, normally there are at least 2.

I use the DAC with Roon. On a Linux endpoint it plays DSD128 via DoP. On a Windows endpoint using the ASIO driver the DAC plays DSD256.

It probably uses vendor specific USB commands to switch between PCM and DSD.

So, I am out of luck then?
