Description Of Issue

Everything was working fine (with Roon 1.8) until I disconnected my laptop from the docking station containing the USB DAC. I continued to use Roon on this laptop to control other zones in the house. When I connected the laptop back to the docking station, the Dragonfly was not listed as a zone.

I checked the audio device settings and Roon can see the Dragonfly - it is enabled. I have tried disabling / re-enabling it as well as restarting roon and my laptop - no joy. I also plugged the DAC directly into my laptop to rule out issues with the dock.

Needless to say, I have used the DAC to playback audio using other software so the DAC is functioning well.

I just connected the DAC to the machine running the Core - it was auto detected and worked fine when I enabled it.

I will wait for a response but at some point I am likely to uninstall/re-install Roon. Even if that fixes the issue for me it’s still a bug (I think).

Uhh, after trying the DF in the Core (and restarting the Core for good measure) I then plugged it back into my docking station. It immediately showed up as a Zone. So I am now back up and running but - worryingly - have no idea what the problem was or whether it will happen again!

If anyone has encountered this before, please let me know!

Sometimes USB devices can get into a state that requires them to be removed and then reconnected to be seen again. I wouldn’t worry about it unless it happens again.

Thanks, but that’s not the response I was looking for. Browsing the support forums reveals a number of people having issues with zones disappearing despite being visible in the list of audio devices (and not just USB devices either).

Like others, I found the issues was resolved after a restart of the Core though this is anecdotal.

Saying “USB devices can get into a state” seems to sidestep the point that this is a Roon issue, not an OS or device issue. It is plainly a defect and ought to be investigated and resolved properly.

Hello @moralcrusader ,

Apologies for the trouble! We’re working on a solution to this and will keep everyone updated here:

1.8 Audio devices in Settings but not in Zone picker [Ticket In]

Hi everyone, I just wanted to let you know that we have a ticket in for this. I can’t provide any specific timelines, but we hope that this will be resolved soon! In the meantime, if you reboot your Core machine your zones should become available again for some time.
