Expected Behavior
When I reopen the selected application in Application Capture, I expect there to be audio from the application as there is when i first select it. Tested with Leauge of Legends.
Current Behavior
No audio from the application is coming into the audio mixer, but audio is coming through just fine via my audio interface. If I toggle show cursor on/off audio works again. I have to do this every time I open the application.
Steps to Reproduce
- Set League Of Legends to Application Capture
- Reopen a game
- No audio
- toggle show cursor on/off while in game to fix it.
Anything else we should know?

Can confirm on macOS 14 with various apps. At first glance this looks like it could be a macOS issue. Will investigate further and report to Apple if needed.
This is a confirmed bug but is also nothing we can fix on our end: The way macOS seems to tap into the audio of an application is inherently tied to that instance of an application (and not the application itself as identified by a bundle identifier). As such when the application is reopened, it obviously presents itself as an entirely different instance to the OS and the capture cannot be restored.
Note that this only applies to the audio portion of SCK as the capture of visible content is handled differently behind the scenes.
Is there an easier way for me to refresh the source manually like I do by toggling cursor on/off? Or is there a special hotkey or something to refresh OBS (like restarting it but without restarting)?
Fwiw I have the same problem on Windows 10, is there a bug for this or should I file one? (e.g. I have to toggle some aspect of Application Audio Capture and back again like any of the Match Title) entries and it picks up audio again.

Windows and macOS have completely different audio capture implementations. I would check the existing Issues and Pull Requests before filing a new Issue though.
