Unable do stream in OBS 27+

[Brayman4k]

Hi! Everytime I update my OBS from 26.1.1 (That always worked really well) to the new 27 version (Including the new RC3), my stream ends randomly and I'm not able to start streaming again if I don't restart OBS.

Here's the LOG from the errors:

It looks like the AAC audio encoder is failing for some reason. You haven't included a complete logfile unfortunately, which includes important diagnostic information (like if you're using ffmpeg output with some honked-up settings that can make AAC crash). I'd recommend enabling the CoreAudio AAC encoder, if you haven't. Here are instructions on how to do that:

OBS-Studio: Enable CoreAudio AAC encoder (Windows)

First of all, if you have iTunes or QuickTime installed, chances are you are already using the CoreAudio AAC encoder in OBS-Studio. But if you normally do not use or install any of those, there is another way to enable it. All we need is the...

Hi! Thanks for the help, my OBS stopped crashing, but for some reason my audio is muting randomly during my streams after installing the AAC encoder.

I'm attaching the full log of my last stream that my audio bugged.

From that log, it looks like Voicemeeter had some issues.
Unfortunately due to the amount of Lioranboard TSL spam it's extremely hard to read that log to tell what's really going on, or if another issue cropped up.
