Roon Bridge is still on v1.7 - it has not been updated. Have you tried to restart your Mac Mini to see if that helps? You might also want to try to play through the internal speakers of the Mac Mini, just to try to identify where the issue is occurring in your playback chain.
I got that point, thats why I tested with iPadOS and Airplay to play on an apple TV. The stuttering issue is same and muisc stops playing after 1 or 2 minutes.
@dylan The latest update after rebooting the core and Mac Mini did not improve. What I found out is my Mac Mini late 2012 has 4GB RAM. I spent some bucks to upgrade the RAM to 16GB and I found the results are amazing. I got the performance back with even higher demanding upscaling to 512 DSD.
I can safely conclude, the new core demands more resources to run smoothly.
Since the performance part is clear, I would like to give feedback on UI/UX. The old one was better and I don’t see any big difference. The folder tree option will only do better for the people who already have sorted the music based on their brain core. Pls consider.
