Topping D10 connected to Core Machine via USB
Description Of Issue
Whenever I hit play on my remote device the sound output on my core machine switches from D10 to Internal Speakers (see screenshot)
So I am not getting any sound out from my D10 DAC
Sorry I should have mentioned the history.
I have set up the audio zone and used the D10 successfully for over a year. This issue seems to happen intermittently and then goes away.
There doesn’t seem to be a reliable fix for it when it happens. I try rebooting the core machine, I try unplugging the D10, I try shutting down and reopening roon server, I even try adjusting settings in Audio Midi setup on my mac mini. Then I give up and play some records and come back a day or so later and it seems to be fine again
You mention you have a “remote device” in this setup, is this another MacOS PC? Does the same behavior occur if you connect the Topping to the Mac remote or does it only occur when the D10 is connected to the Core?
a 2010 Mac mini is woefully under spec for a core machine…I would only use this spec Mac as a roon bridge endpoint. Try to run a core on a better machine then see how it fairs
So the remote device is a MacBook air.
When I plug the d10 into the MacBook air and configure it (via audio > settings) as an output for the D10 it works without any problem.
Plugging the D10 back into my core machine results in no sound.
As another data point, if I play something directly on my core machine, say on youtube, I do get sound through the D10
Just to be clear, when the D10 is plugged into the core machine, my remote device “thinks” music is playing - the time advances on the progress bar down the bottom - but no sound can be heard
Did you ever use Time Machine to restore the live Roon backup to either of these Macs?
Using Time Machine can cause this behavior and we do not recommend restoring the Roon live database through it, as mentioned in our Backup documentation.
If you haven’t used Time Machine, do either of the Macs have a Touch Bar installed? That’s possibly another reason why this behavior can occur.
No time machine backups have been done and neither machine has a Touch Bar (the core machine is a Mac mini and the remote machine is a MacBook Air that predates any Touch Bar)
