What best describes your playback issue?

· My DAC, streamer, or speaker doesn't appear as a Zone in Roon

What type of Zone is affected by this problem?

· *Network Zones* are affected.

Is the affected network Zone connected with Ethernet or WiFi?

· WiFi

Which network audio protocol is the Zone using with Roon?

· RoonReady

Does the device show up at all in Roon Settings -> Audio?

· Yes, it shows up there, but it isn't Enabled

Does the "Enable" button unlock the Zone?

· I pressed Enable, but the Zone remains disabled

Does the device play audio from another source when using the same connection?

· The device has no problems with another audio source

Have you checked that Roon is whitelisted in any firewalls?

· I've checked the firewall and the issue remains

Since you are using a network connection to the device, please ensure that your RoonServer is on the same subnet as the device

· My devices are on a single subnet but is not visible to Roon

Do you have a complex network setup?

· I don't have a mesh network, but I use *managed network switches*

Try to disable any additional networking interfaces on your RoonServer machine.

· Disabling network interfaces had no change in behavior

Check to make sure RoonReady mode is selected on the device.

· I've checked this and the issue remains

If the device has multiple output options, do the other options work as expected?

· Only one output type is affected while the other output type works as expected

Is the device using the latest firmware as per the manufacturer?

· Firmware is up-to-date but the issue remains

Do you have an approximate timestamp of when the issue last occurred?

· May 3rd, 11:59am ET

What are the make and model of the affected audio device(s) and the connection type?

· Holo Audio Cyan 2, connected to Raspberry Pi 4 set up as RooExtend

Hi-

Just to provide more information, I have a Holo Cyan 2, which works perfectly as an HQPlayer endpoint over NAA via a RooExtend streamer. However, it won’t appear via ALSA as a normal Roon endpoint. I enclose a series of screenshots below showing that when RooExtend enables both RAAT and NAA (or just RAAT and not NAA, I’ve tried both), it appears in Settings / Audio. When I click on it, there are 3 levels of Holo Spring that appear as possibilities. Whether I click any of those 3 or the “My device isn’t here”, the result is the same - the device appears but says “Device not found” in red. When I click on the gear to change settings, it offers only the choices “Disable” or 'Retry" so there’s no further settings available to change.

I’m fine for now - I can play music via NAA / HQPlayer, which is why I purchased the Holo Audio Spring, but I thought it was strange and would like to resolve because I don’t always have my HQPlayer running.

For what it’s worth, I have many other endpoints - Denon AVR via AirPlay, Sonos, RooExtend → Schiit Yggdrasil, RooExtend → Schiit Bifrost 2, and all work fine. I’m not concerned that my network is not working.

Many thanks for your help.

It looks to me like rooExtend is showing in Roon. The device not found is then a message sent by rooExtend. Probably check the settings and configuration on the rooExtend? Also is the DAC connected by USB to rooExtend set to the USB input and turned on?

Contact the author of rooExtend about it?

Hi thanks BlackJack. Yes, you can see above in the screenshot that the RooExtend (which is just acting as a RoonBridge) is passing the Holo Cyan 2 and advertising it as an available device to Roon. If the power of the device is off, or its not plugged in, then nothing appears in Settings / Audio.

Ok, bizarrely, after 10 days of struggling with this, it just resolved. I swear I didn’t do anything different. It just eventually, well, umm worked.

I would love to know if anyone from Team Roon has a clue what happened, that made it break, or what made it resolve. But it’s settled so no need to chase this one unless it recurs.

Thank you!

And… though I bought this DAC to do HQPlayer upsampling, it makes for a lovely NOS R2R DAC with redbook. Have been enjoying it this way all evening.

Hi @Johnny_Ooooops,
Thanks for letting us know you were able to resolve the issue with the Cyan 2. It’s always great to hear things are working again!

It’s tough to pinpoint the exact cause after the fact, but based on what you described, it does sound like a network-related issue—possibly something as simple as an IP address assignment or a temporary network hiccup. If anything similar crops up again, feel free to reach out and we’ll dig in further.
