If your audio is muting when you launch OBS, and you're using a Bluetooth headset, it's caused by the underlying design of Bluetooth.
Bluetooth headsets typically have 2 modes, stereo audio (A2DP), and headset (HFP - Hands Free Profile). These two profiles have separate audio devices on the computer side.
When you have OBS set to activate a Bluetooth headset's microphone, that causes the headset to automatically switch to HFP mode, as A2DP is a lower priority. The reason your audio mutes is because it's still being sent to the A2DP device instead of the HFP device.
To fix this, you either switch to a wired headset, don't use the Bluetooth headset's mic, or set your sound to go through the HFP device for your headset.
Note: HFP offers lower sound quality.
OH MY GOD THANK YOU MAN I HAD THE SAME PROBLEM AND THIS FIXED IT :DThe bluetooth headset is EXACTLY why things are breaking.
I had the same problem. The solution is to turn off audio monitoring.
OBS Settings > Audio > Advanced: Monitoring Device. Change the monitoring device to something other than your headphones. After that, it should be gone.
I was coming in to say exactly this. I'm using OBS as a workaround for Camlink not working with browser based video conferencing stuff like Google Meet. I've got a Blue mic and I use my Pixel Buds to monitor the call so I don't have to wear my AKGs. So yeah, disabling the mic is perfect for this use case.Go to OBS settings > Audio > Global Audio Devices
Now change Mic/Auxiliary Audio from default to other options.
This fixed my problem.
I couldnt hear anythig my bluetooth device but OBS was still recording the audio. Now its working perfectly and I can hear audio with bluetooth headphone.

If you switch to HFP audio, does OBS also record the low-quality sound?The bluetooth headset is EXACTLY why things are breaking.
AHH THE AUDIO MONITORING.And you did try all of the above? Audio Monitoring set to Monitor and Output, changed Monitoring Device, changed Global Audio Devices, stopped using bluetooth headset? Then please create a new thread and provide a log file. Here's how.
