Description Of Issue

Music from Zone 1 (described above) drops out and then stops, or will not start intermittently on a different day. Sometimes when the dropout completely stops the music I will hear a very scratchy sound then the music stops.

Zone 2 drops out when using iTunes relatively low bandwidth. This is confirmatory that the issue is Roon or Roon HDW related and not something specific in Zone 1, Sonore or UpTone Audio product, I think.

I appreciate any help…I’m pretty addicted to music in System 1.

Hello @thotdoc,

Could you try using the Mac as your Roon Core instead of the Sonic Transporter to help us localize this issue?

To do this:
A) Start the Roon app on your Mac.
B) Go to Menu > Settings > General > Disconnect from SonicTransporter Core.
C) On the “Choose Your Core” menu, select “Use this Mac”.
D) Log into your Roon Account.
E) When it asks you to de-authorize the SonicTransporter, go ahead and do so. Your database and music on the SonicTransporter will not be affected.
F) Log into Tidal and or Qobuz, and set up your playback zones.

Once you’re up and running, try playback from the Mac core to the opticalRendu zone. If playback is stable with this setup, we can focus our attention on the SonicTransporter.

Have a wonderful holiday.

@thotdoc do you mean EtherREGEN? And if so the optical (SFP) is on the A side still, not the B side.

I think the problem was a Cisco switch I have now taken out of the chain. If this doesn’t work, I will get back to you.

Again, thank you.
