As the title says, I’ve been using a USBridge with DietPi for 2 years now, for the first 18 months it was great, would stream for days at a time from Roon, but the last six months no dice.
After a software update at some point, everything got super flaky. Flaky as in stream will always die within about 30mins to 5 hours. Roon core is a Mac Mini on ethernet, USBridge is ethernet as well. Already tried wiping the USBridge and starting fresh, but didn’t help.
Not sure where to look to troubleshoot, but I did check the /var/log/roon folder and the RAATServer_log.txt file had this after a recent stoppage. Started playback at timestamp 02/12 02:52:03, then it died at 02/12 03:21:51. Roon core is 192.168.1.20. Is there a log on the Roon core side I can check as well, or another log that would be better in DietPi? Thanks!
