I am running roon server on a QNAP TVS-682. my music database is 650GB. importing music through mac music into the dedicated folder on my server (so I have my iPhones/ipods updated). roon reads the file and adds to its database.
QNAP is connected by HDMI to my Yamaha RX-A3050 which plays on my 5.2 speaker system wired.
I have 4 more Yamaha musiccast speakers in the house, connected through wifi.
Everything worked fine until some 4 weeks back. I can still play all music on my iTunes/macmusic on all speakers.
roon recently decided to behave exactly the same way like described here. just not playing anything.
