After months of glorious Roon performance I came home and turned on my mid 2011 MacMini running 10.12.6 and opened Roon Version 1.3 (build 269) stable (64 bit) to find the “No Audio Devices Found” message. Below that message is an option to Manage Audio Devices. I select that option and what I see is “Networked” and an option to add HQ Player. No options for my NAD D1050 headphone DAC as when I originally setup Roon. I am not running any third party anti-virus, etc. I can’t find my NAD DAC anywhere in settings. When I open Roon I can still see all the Playlists I’ve created, the queue is still there etc, nothing will play. I am playing the Tidal desktop software through the NAD headphone DAC so I know that works. I normally play music through Roon from my QNAP TS251 NAS and Tidal.

Please help, I need my Roon back!

It showed as “uncategorized”, so I just categorized it in the Support thread. What thread did you try to post it to?

Does music play with any other player on the Mac mini? Did something happen to the audio devices to disable them? I am not a Mac dude so…not sure if this helps…

I unplugged the USB cable from MacMini to NAD DAC and plugged in an AudioQuest Dragonfly into the same USB port on the Mac and I unplugged and plugged back in the network cable to the Mac (did not power cycle the Luxul switch or router). After that the Select A Zone option returned, went into Device Setup and was able to see the Dragonfly. Reconnected the NAD DAC USB cable in place of the Dragonfly and the NAD DAC also showed up and playback is back to normal. I appreciate your help and will report back if the issue persists.

Hello everyone, I just renewed my Roon subscription but I’m still having the same issue that when I open Roon it does not see my NAD D1050 headphone DAC, the core is my MacMini. I have the MacMini’s ethernet port plugged into a Luxul XGS-1005 5 port switch which is connected to my Luxul XWR-1750 router.

If I power cycle the switch Roon then see’s my audio device. This switch power cycle seems to solve the problem more consistently than unplugged the USB cable between the MacMini and the NAD DAC. In device settings > Playback tab I have “Use Exclusive Mode” and “Use Integer Mode If Support” turned ON.

Any thoughts on what is happening and how to remedy this would be appreciated. Thank you.

Hey @SJC ,

Have you tried to bypass the switch ? If not, can you try to remove it from the chain for a couple of days and see if issue appears again ?

Regards,

Hi Vova, yes I bypassed the switch but with the same issue persisting. As soon as I unplug the ethernet cable going into the MacMini and plug it back in the audio settings pop up and show my NAD DAC. I also tried using an AudioQuest DragonFly DAC with the same issue. I have a feeling it is something with my MacMini hardware or possibly the NAD DAC itself. Refreshing the network connection solves the issue every time but it is annoying.

Any other suggestions are welcome and appreciated, thanks again.

Hello @SJC ,

Apologies for a slow response here. Do you have any other machine you can temporary use as a host for a Roon Core ? If so, would you mind trying install Roon there, connect the DAC over USB and see if the same issue occurs ?

Thanks,

I have a PC running Windows 7 PRO, with Roon running as a remote. How would I go about making that machine the core? I also have a MacBookPro with no Roon installed. I should mention that this problem just came up a couple of months ago. Do you think it is network related or something to do with the specific computer that is running the Roon core?

I think that this is the problem with MacMini, switching to another machine should confirm or deny this theory.

For Win7 machine:

  • Launch Roon
  • Open General tab in Settings
  • Press Disconnect button
  • Login your Roon account
  • Roon will prompt you to deauthorize the previously active installation.
  • Press Unauthorized button
  • For MBP:
    Just install the app and deauthorize the previously active installation.

    By de-authorizing the previous active installation does that mean that the core is switching from the MacMini to the Win7 machine (through the process of disconnecting and logging back in again). Currently the Roon on the Win7 machine is installed as a remote. I think using the Win7 machine is a good test as it is plugged into the same switch as the MacMini.

    Thanks.

    Ok, so I deauthorized the MacMini as the Core and have the Core now on my Windows 7 Pro machine. I have my NAD DAC connected via USB to the PC. When I go into Audio settings in Roon I see an option for NAD USB Audio ASIO Driver with an Enable button, pressing Enable generates an Error: “Error Loading Device Info: DeviceInitFailed”.
