No system outputs available in Mac OS 12.5.1

Recurring problem per described here No system output in Mac OS 11.6.3:

Roon Core Machine

Macbook pro 2018

Networking Gear & Setup Details

Connected Audio Devices

Using built-in output

Description of Issue

I am using the macbook pro as core and output device.
There are no system outputs available in settings/audio (external output, loudspeakers, system default, etc). I only see a network audio device (rpi). I have the latest version of roon.

Any definitive solution for this?

Quick question, have you tried updating to 12.6 and see if that resolves the issue? I use a 2019 MBPro for my Core and have not had issues with either release, but 12.6 may help.

Hi @Elece,

Any luck with getting things working?


No, updating to mac os latest version, didn’t solve the issue.

Any updates on this? Has been an issue for many months and as I mentioned, in the meantime I did a clean MacOS reinstallation, so it’s a roon issue most probably.

Hi @Elece,

I apologize for the slow response. Somehow your last post was buried and I greatly appreciate your patience.

One of the things we have seen is that ALL audio devices are missing on Mac OS when the computer is set to sleep.

Under system preferences > energy saver, how are things set? Here’s what mine looks like and what it should look like for Mac core users. There was something we’d refer to as a bug in 1.8 or earlier versions where the application was preventing the sleep on its own regardless of the settings and is a possible explainer for the behavior you’re observing.

I have the same settings, but the problem persists. I think it happens when there is audio already playing from some other app and I open roon. Like I said, it’s a bit random.


I am curious as to whether or not there is corruption in the application causing this because you aren’t the only one this has happened to.

Will you please try a fresh install via the method below and try to duplicate the issue?

  • Create a Backup of your current database
  • Exit out of Roon
  • Navigate to your Roon Database Location
  • Find the folder that says “Roon”
  • Rename the “Roon” folder to “Roon_old”
  • Reinstall the Roon App from our Downloads Page to generate a new Roon folder
  • Verify if the issue persists on a fresh database before restoring the backup

Hello Wes. Reinstalling doesn’t solve the issue (with or without using the backup). Energy saving settings don’t have anything to do either I guess, because I’ve sitting for 10 minutes using the computer while doing the installation and the system output isn’t showing either. At this point it is clear there is a bug in roon core accessing local Mac Os audio drivers or something like that. Please try to get this issue up from the backlog, it’s been going on since march and it’s really frustrating.

Hi Elece,

One question for you. Are you by chance using Time Machine and/or was it used to restore a backup here recently?


I am using Time machine. I honestly don’t remember if I restored roon’s backup from time machine or from my cloud backup when I did a fresh install a few months ago. When I restored a few days ago, it was a local backup, no time machine/cloud used.

Ok, I have an idea. I will message you. Please let me know if this fixes it for you.


Just to add, since reinstalling, I haven’t been able to select local system outputs. Before, there was a 50/50 chance that when opening roon the outputs would show, now they never show.

Hi @Elece,

Thank you for reporting back. I am working on collecting some instances of this (we have only a few) but we’ll be attempting to duplicate it on our end.

To clarify though, you did rename the Roon folder and installed fresh with no import of your database and the issue still persisted?

Can you show me a screenshot of your audio outputs in system preferences? This is Ventura’s new view of my settings

Yes, I looked before and after retrieveing the backup and no output shown in roon’s audio section.
Here is mac os sound section:

Thank you for the screenshot, @Elece.

I will be discussing your case (and some others) with our development group today to see what we can do on our side.
