Roon Core Playing Music on MacBook While Using ARC Causes Issues (ref#N4LEQS)

Hi! What’s not quite right with Roon?

Tell us what's going on

· I’m new and have two issues:
1) I downloaded ROON Core to my MacBook Air Pro. The issue is that when I leave it open and logged in, and then use Arc in my car- apparently music plays at my house as well. I know this because my wife came home and complained that ROON was playing too loud and she couldn’t figure out how to turn it down so she closed the laptop which logged me out and then Arc no longer worked in my car.
2) The previous issue led to my second problem. When I got home I opened the laptop and it appeared to be logged in. But, apparently ROON was frozen. I re-logged in and ROON was still frozen. I then rebooted my laptop and logged back in and everything worked.

How can I solve these issues? Thanks in advance.

Hello @1p2win,

Welcome to the Roon Community, and thanks for the detailed explanation — that really helps

A couple of important clarifications first:

Roon ARC cannot control or trigger playback inside your home.
ARC is a remote-only app designed for listening outside the home. It has no ability to start, stop, or adjust playback on your Roon Core or any local zones. Because of that, the music playing at home while you were using ARC was a coincidence rather than a direct interaction between ARC and your Core.

If Roon was already playing to a local zone on your MacBook (or another zone at home), that playback would simply continue until manually stopped. ARC connecting remotely would not affect it.

When your wife closed the laptop, macOS likely put the system into sleep/hibernation, which abruptly stopped the Roon Core. Since ARC depends on the Core being online, ARC then lost connection in your car — which matches what you observed.

Force-closing or sleeping the Mac while Roon Core is active can sometimes leave the Core in an unstable state.
This behavior is consistent with an interrupted Core process rather than data corruption.

To help us understand whether there’s anything deeper going on, please try the following:

  • Reproduce the scenario:
    • Start playback locally
    • Leave the MacBook open with Roon running
    • Connect via ARC from outside the home
    • Then put the MacBook to sleep or close the lid
  • Note exactly what happens:
    • Does Roon freeze again afterward?

If you’re able to reproduce the issue consistently, let us know and we’ll be happy to pass this along to our QA team for further testing.

As a general best practice, if you plan to rely on ARC regularly, we strongly recommend running Roon Core on a device that stays always on (for example, a desktop, NAS, or Nucleus), rather than a laptop that may be closed or put to sleep.

Looking forward to your update — and welcome again to Roon! :musical_notes:

Hi @1p2win,

Just to clarify, the most likely culprit here is that the laptop closed, which severed Roon’s access to the network interface.

When Roon was frozen after re-opening the laptop, did you notice whether RoonServer was running in the background in the menu bar? It sounds like the GUI (Roon Remote) froze but the server remained online.

We’ll watch for your response. Thank you!

Thank you for your response. I’m not sure what was happening when I re- opened the laptop.

But, my work around is to close the Roon app on my laptop before shutting it down.

I also ordered the Nexus One - which I hope will make things easier for me and- importantly- my wife.

@1p2win,

Thanks for confirming the solution you found.

Running Roon Server on a dedicated machine (always-on) is indeed considered best practice and often provides the most stable experience.

Regarding the other points you raised:

Freezing after Sleep

You should not need to force-quit Roon every time you put your MacBook to sleep. If the application is consistently freezing upon waking, that is not normal behavior. If you continue to see this happen, please let us know so we can investigate it further.

Roon ARC Usage

Standard ARC streaming requires your Roon Server to be online. However, if you want to listen while your server is asleep or shut down (e.g., in the car), you can use Offline Mode.

To do this, you must download the content to your phone via ARC before the server goes offline. Once downloaded, those tracks will be available for playback regardless of your server’s status.

Thanks.
