Audirvana for Linux release

My favorite DAC player Audirvana just released a beta version for Linux and QNAP:

I currently use a Mac Mini to run Audirvana and play the audio to my DAC, but it would be great to just let the NAS do it for me. It’s a headless install meaning there’s no GUI needed, all is managed via the Remote app.

The release is available as a Debian or RPM package.
Is there any way to let an App in TrueNAS Scale have access to the USB port?
Thanks.
