Issues with Audio Recording DAWs

Hello!

I've been having this irritating issue with OBS where desktop audio capturing has been constantly disabling while recording. From what I've gathered, it seems that the desktop audio capture will disable whenever either of my daws (FL Studio 25.2 & Ableton Live 12.3) cpu overload temporarily. This has never happened before until about a month or so ago. I believe this might likely be a Mac OS 26 issue that has not been resolved yet. Any work arounds or fixes would be amazing!

Specs:
2022 Mac Book Pro
Apple M2 Pro (10-core CPU, 16-core GPU)
16gb Unified Memory
Mac OS Tahoe 26.3
 
The desktop audio source on Mac uses a CoreAudio process tap that can silently disconnect when the audio subsystem hiccups -- and it doesn't auto-reconnect, it just disables itself. A DAW CPU spike causing a brief audio dropout is exactly the kind of thing that severs the tap. A workaround that's worked for others is routing the DAW output through BlackHole (free virtual audio driver) and capturing that in OBS instead of using desktop audio capture directly, since BlackHole stays up even when the main audio session drops.
 
Thank you so much, I will take a look at that. Is this change to CoreAudio recent? I've only started having this problem right after updating to Tahoe.
