Question / Help How to record audio coming into headphones (but not pickup mic)

[aginton]

I'm new to using OBS, so sorry if this is obvious, but I haven't been able to work it out so far:

Suppose I'm video chatting with someone and have headphones plugged into my PC. How can I record the audio coming while not picking up anything from my mic?

It's not clear what exactly you ask. If you want to exclude your mic from being recorded by OBS, you can remove it from the audio sources in Settings->Audio. There is also a meter for all sources OBS knows, where you can set the volume of each source as well as completely mute the source.
