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

Same here. Very inconsistent and frustrating. I have a lampizator pacific which I turn off when I’m done and turn back on when ready. Roon seems to forget about it and not see it when it comes back up. It was instantaneous in 1.7. Ugh… Does anyone have a workaround for this?


I have this issue also. This is a huge deal breaker for me. And there’s another one but it’s not the topic of this discussion.

Looks like issue is fixed. I got all zones back.

Same here. I have Mac mini and RME ADI-2 fs.

I just had a zone disappear after a screen freeze on an Android 9 remote.
Reboot of ROCK brought it back.
Momentary annoyance.
Trust that Roon guys will kill the bugs.

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.

Thanks for the update.

I keep losing my Audio-gd amp/dac (usb connected to laptop running Roon). Rebooting NUC (ROCK) brings it back. This time its dropped while sitting on laptop screensaver for a couple hours. Everything powered up, no standby. Nothing was turned off. Turning pc/dac/ off/on had no effect.

Description Of Issue

After upgrade to 1.8 everything was working fine, then I lost connection to my SMSL DAC. When I verified that I could connect to the RPi via ethernet, I noted that there was an upgrade availalble to Ropieee. I upgraded Ropieee to the latest version, but this did not resolve the issue. I then rebooted the Roon server software, and the SMSL DAC re-appeared. All good until today, when it disappeared again. I rebooted Roon server software again, and it re-appeared. Connection had been stable under 1.7. Any suggestions?

Hi @Mark_Pocock ,

Does the same issue occur if you try to connect the DAC directly to the Roon Core?

Can you please provide some more details on the networking gear?

Hi Noris
Thanks for the quick response. Not having the issue at the moment, can turn the DAC off and it disappears in Roon, turn it back on and it reappears. Next time it fails to appear, I will try connecting directly to Roon Core.
Networking Gear:
Roon Core connected to TP Link SG 105 Gigabit Ethernet Switch, which is connected to
TP Link SG1016G Gigabit Ethernet Switch, which is connected to
DLink DGS-105 Gigabit Ethernet Switch, which is connected to
Raspberry Pi 3 running Ropiee



Also check in the settings about to see if the ropieee/roon bridge is listed.

@noris thus is not the first I’m seeing of devices disappearing and a core reboot resumes visibility

I have similar issue since 1.8. Never experienced this before.
In my case, I have Audio-gd Di-20HE connected to Rock (NUC8) via USB, however when I turn on NUC and Di-20HE, sometimes it doesn’t appear in the playback device list. then I go to settings → audio, and I can see the device in the list “Connected to Core”, but not available to pick in “Select an audio zone”.
This is odd, if it is in the list of connected to the core, should be available to select as an audio zone.

If I restart Rock server software via web UI, then I can see Di-20HE in list of “select an audio zone”.

I have the same issue with windows10, each time ı should restart the room server in order to reach at the usb end point.

I flashed my problematic HifiBerry back from Ropieee to HifiBerry OS, so I think I will be spared from this issue from now on.

I have the same issue with a Pi4 running Ropieee, windows server needs restarting before I can set the audio zone, I can see it in the settings audio.

Can I ask how it was fixed. I have the same set up as you and am having the issue?

Thank you. Just wanted to provide a screenshot showing the issue! Can you please contact me with a fix once it is available. Screen Shot 2021-02-12 at 10.53.13 AM|595x500

I’m seeing the same issue here. Rebooting the core fixes the glitch, but only temporarily.

Linux core, macOS app, USB DAC connected to the Mac.
