Getting Error "unexpected error communicating w/ audio device" - Roon working w/ Tidal on a Mac

Description of Issue

Roon has been working for over a year now, and this error just began. I keep the MacOS, Roon and Tidal all up-to-date. So all versions should be the latest releases.

Hi! Did you try rebooting the Mac and the amp?

[Bernd_Kurte (Bernd)]

And on top of that try another USB cable.

@Suedkiez

try rebooting the Mac and the amp

@Bernd_Kurte

another USB cable

3. Do you have same problem when used as osx system output?

4. You can try a Roon bridge device to see if the problem goes away.

5. Or try to kill core audio

6. Or try to reset RAAT server

sorry as I do not find the 4000n on google (is it 400s or 400sn?). Or in 4000N, “N” stands for network?

Rebooted EVERYTHING… modem, router, iMac, Amp

Hi @Mark_Pecoraro,

Do you encounter any errors playing to the system output of the iMac? Recent logs show playback errors on networked endpoints, suggesting there might be a more widespread issue with the output path.

We recommend first refreshing RAATServer on this Core to stabilize conditions:
You can generate a new RAATServer instance on your device by following these instructions, but please be aware that this will reset your Roon Settings → Audio Tab to factory settings and I would advise making a backup of any custom DSP settings you have:

• Create a Backup of your current Roon database
• Exit out of Roon
• Navigate to your Roon’s Database Location
• Find the folder that says “RAATServer”
• Rename the “RAATServer” folder to “RAATServer_old”
• Restart the Roon App to generate a new RAATServer folder

@connor , I followed your instructions, but the problem still exists. In fact, it is now much worse. I can’t get anything to play. I don’t have any other audio issues on my iMac, using the system output or an external USB to integrated amp. All apps/web sites have expected output without issue. Not sure what to do from here. I can use Tidal directly without any problems.

Hi @Mark_Pecoraro,

We’re very sorry for the delayed response. Can you please submit a screenshot of your Device Setup page for this USB device by navigating to Roon → Settings → Audio and clicking on the gear icon? Please expand the menu to “show advanced.”

We’re also curious about any Zone Groups you might have created. Diagnostics indicate two-channel content is reaching your Zone as multichannel - there’s a potential channel assignment issue here.

Also, do you have any DSP engaged for the Gato?

Hi @Mark_Pecoraro,

I wanted to check in on this issue before it auto-closed. Did you see my previous comment above?

[Mark_Pecoraro]

Connor, THANK YOU for the follow up. Here are the screen shots that you requested. Might I try getting rid of ALL endpoints and starting over? I only have 2: my iMac feeds the USB into the Gato, and 2) my Cambridge 851 in my living area?

Please advise. I love love love Roon when it is working. I have to figure this out… it is really getting anoying…mark

[Rugby (aka Daniel or Big Dan)]

I would break up the group, and try playing to each zone individually first and then simultaneously but not grouped.

Hi @Mark_Pecoraro,

How’s it going? Did you try to isolate the Zones as our moderators suggested? We’re here to support if this issue is recurring.
