MERGING+PLAYER is a MERGING+NADAC with built-in NUC and ROCK, including support for AES67 implemented by MERGING. This is the only way how you can get what you asked for and that I’m aware of.
ROCK is distributes as is and doesn’t allow a user access (to install an additional driver for example). RAAT is developed and owned by Roon Labs.
None of this hasn’t been already asked in the past. See also:
But I have no clue if this driver for Linux is available, open-source and still maintained/working.
