Question / Help Audio Levels Even When Mic Is Off

[Jade Sambrook]

The Mic/Aux levels on the Mixer panel in OBS keep registering audio (although a very small amount) even when my microphone and mixing board that are plugged into my sound card are turned off.

Why is OBS registering audio levels if the mic and mixing board are turned off? Is it possibly because my sound card is picking up noise from the PC fan?

I would love it if the audio levels for Mix/Aux would be at zero when my mic and mixing board are turned off, otherwise I think that something is wrong and that my audio quality will be affected by some type of interference.

Is there a solution or a setting somewhere that I missed? Am I doing something wrong?

My soundcard is a Soundblaster Fatality. My mic is plugged into my Yamaha mixing board and my mixing board is plugged into my soundcard at the rear of the PC.

Thanks for any help if you know what the issue is :)

It's probably just picking up the sound from your internal computer mic, not the sound card. There might be an issue with some external sound-cards, I'm trying to record a mic through a MOTU 4Pre soundcard, but it can only hear the internal mic for now.

It probably is interference. Make sure everything's grounded properly and you don't have any ground loops, and make sure you've got nothing putting a lot of RF noise into the area.
