Question / Help Always a crackling sound in background of audio only when using OBS

[Swizzle]

So, I've had this issue for about a year.

Since I started using OBS Multiplatform/Studio, there has always been a crackling sound whenever I record or stream. After reading countless forum posts, I was always under the impression that it had something to do with my microphone. That's what the answer seemed to be with others that had similar problems.

I just bought a brand new Audio-Technica AT2020USB+ microphone, thinking that it was going to be the answer to all of my problems.

Here's the thing: I still get the same exact crackling no matter the microphone. USB, plugged into the motherboard audio input, etc.

This is an example I just recorded using OBS with the AT2020USB+ mic:

The kicker is that, as stated before, this only happens when I use OBS to record or stream. Here is another recording I just made using Sound Recorder:

I don't get it. This is a problem with something in OBS. I dunno what. I dunno where to even look.

And yes, I have adjusted the gain/noise suppression/noise gate filters and they don't help at all.

Anyone... please... this is just driving me up the wall. I've ignored it for a year but man, my brain fries each time I boot up OBS to record or stream.

Here is my current log file, it it helps: https://gist.github.com/063e4dd5c8d6ac6bee20cab5947fe941

Any help would be appreciated

Ok, I figured out what the issue is and I'd like to request support of some kind from anyone in development of OBS Stuidio:

It turns out that the constant crackling, that I've been experiencing for over a year, is due to having my Mix/Aux set to PUSH TO TALK.

There are no buffering delays set. Just having the Push to Talk bind set causes the constant crackling that's heard in the first video above.

Can someone on the development team try to duplicate this?
