Description of Issue
The first indication of a problem was that I could play a few songs, but at some point I would select another song it wouldn’t play. I had to turn off my Oppo UDP-205 and turn it back on to regain control of playback.
This got progressively worse until I could only play one song and then I would have to cycle power on the Oppo to regain control.
I decided to reinstall Roon on my QNAP NAS to see if that would solve the problem. After reinstalling Roon I was able to switch between songs again, but the vocals sounded very distant on any song I played.
After playing about 10 songs I began losing control of playback again. This time I was not able to regain control of playback. Actually, it appears that playback is occurring when I look at Roon on my phone, but the Oppo UDP-205 is not producing output (and therefore seems to not be receiving input from the Core.
This morning I updated the Roon Core on the NAS (I think it was already up to date) and this did not restore playback. I also tried cycling power on the Oppo and this did not restore playback.
The main problem is that I can no longer play to my Oppo. The secondary problem is the distant sounding vocals that occurred prior to total loss of control.
That looks to be a managed switch. Roon advises to use un-managed switches. While I don’t see your model on the list, take a quick read of the network faq, and at the bottom with suggestions for specific router models, see if your model(s) have settings dealing with Multicast and IGMP and if they make a difference.
Yes, my Oppo shows up under Roon Ready in the roon app on my phone. However, it doesn’t show up under “Connected Audio Devices” in the Roon Server Overview screenshot when I open the server on my NAS. Should I see it in this window too?
Okay sorry, I assumed it was a new install with issues.
In that case, I would suggest loading Roon temporarily on a different PC (windows or mac) and see if it has the same issues. If it does not, then continue looking at the Qnap, if it still has the issues with the other PC, then it might be the Oppo’s network port, (or the cable or the network port on the switch).
I installed Roon server (Core) on my Mac and everything worked fine. I was able to stream to the Oppo and other devices. I then switched back to the Roon server (Core) on my QNAP NAS and everything worked again. So it remains a mystery why things stopped working before.
