Roon ARC non functional on Shanling M7 and other bugs

Description of Issue

Loving the idea of Roon ARC so far, but I’ve encountered 2 issues thatprevent me from truly enjoying ARC. For one, I am 100% unable to play any music on my Shanling M7, everytime I try to play something, the track will load for about a minute, then the error “Playback: Internal error” appears. This haoppens for all songs. As for the Samsung S21 Ultra, it will play music, but only in a maximum of “high quality” mode even when the audio is beingpolayed through the external DAC listed above in the audio devices section. Anyone have any ideas of what’s going on?
