OBS is cutting off my audio

I can't hear anything as soon as I open OBS. My music and gameplay sound just became silent when they were still continuously playing. I tried uninstalling and installing again. It didn't fix the error. Help me please.

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.
