Question / Help The audio is echoing when unmuted, no YT videos with solution

[Joseno]

My current predicament is that I would like to record the audio from my desktop alongside the video. However, whenever I unmute OBS in the volume mixer, I can suddenly hear audio from myself. It isn't from my mic, it's from my output device whether it be my laptop or my headphones when I plug them in. This even persists when I have all audio channels disabled on OBS.

I've accidentally solved this problem before, but the problem came back the very next time I opened OBS. Could I get some help to find a solution or at least a temporary one that I can remember to repeat?

You have your monitoring device set to your desktop device. Make sure you don't have monitoring enabled on any audio sources in the Advanced Audio Properties (click a cog in the mixer to get there). You can also try setting your monitoring device to an unused output in Settings->Audio.
Additionally, if you are livestreaming, DO NOT watch the stream from the same system you're streaming from, or it will create an audio loop.
