Question / Help Noise gate while using a mixer

I am using a dual pc setup and notived that using the included noise gate features in obs tend to cut off other sounds I have going through the same audio path in obs. I have my desktop audio in one track, and my mic/teamspeak/music on another track. all of these 4 tracks are all on separate channels on the mixer. I tried routing the teamspeak and music channels to the post fader aux on my mixer(desktop audio is set up to output to the stream pc through pfl aux and remains muted on alt 3/4 on the mixer)) then back ran into issues with them showing up in the same track as the mic as well as their own track in obs when trying to keep all of them separate in the software This happened anytime the mix was unmuted even if there was no way for the mic to be picking up the extra audio, maybe I am doing it wrong though. I thought about using a virtual cable and an external program for noise gating just the mic input and am playing around with that to see if it works. but any help would be great in getting my final mic settings finished so I can get back to streaming asap.

It's not something that is going to show up in a log per se. All my my audio is input through a mixer, so using the usb audio codec to input my mic ends up with me not having the option of using a noise gate because it will then affect all the audio coming through the mixer and not just the mic. I have an idea though and am going to try a different routing option for my audio and will report back

The log file was more about dealing with the problem of all of the audio showing up on the same track, but if you're only using one input from the mixer then clearly that's why that's happening.

Exactly. I am using a Behringer 1204usb, ch1 is my xlr at2020, ch 3 is teamspeak audio being output from my gaming pc using its own independent output on the gaming pc, stereo ch 5/6 is my desktop/spotify audio from main gaming pc output. I have my mic set to aux out 1 (pre fader) to return to the gaming pc for game and teamspeak communication. I have the behringer mixer connected to streaming pc via usb, and the mixer is output currently via alt 3/4 output using 2 ts cables to the 2 inputs on a presonus audiobox usb interface. In obs I have the audiobox set as one input, and the mic is set using its own input via usb audio on the mixer.

I have to keep my ch 5/6 desktop and ch 3 teamspeak on alt 3/4 all the time to keep the channels separate from the mic in obs, which allows me to use either noisegator or the obs noise gate on the mic only. My issue is that if I want to mute(alt 3/4) my mic on the mixer then it gets sent to the other audio track in obs and vice versa if I unmute(alt 3/4) my desktop or teamspeak audio it gets sent to the mic track in obs.

My goal is to be able to be able to use the mixer to mute desktop and teamspeak audio using the alt 3/4 so I can still monitor the sound without sending it to the stream, so I thought about hooking the mixer to the main outs instead of alt 3/4 outputs but it then goes back to the issue of all the audio then gets sent into one track in obs when all is unmuted which leaves the noise gate features useless as it will be noise gating teamspeak and desktop audio as well as the mic.

Any thoughts? I will post edit in a logfile in just a moment.

As far as muting your mic goes, what I'd suggest is that you adjust the gain knob on the mic input so that your mic is at the level you want when the fader on that channel is at unity (zero), then when you want to mute the mic, pull the fader all the way down. This way you don't need to remember where the fader was, because you know it was at zero. You're not going to get a proper mute because as you've found, the mute function on those mixers doubles as routing to the alternative outputs, and you're already using those.

I think your problem is that you're trying to do more things with the mixer at once than it's capable of.

Thank you a lot for your help. I actually figured it out and it was very simple lol

My solution ended up being splitting the aux 1 output I was using to send the mic to my gaming pc and plugging it into both the stream pc and gaming pc after the headphone splitter. I can now leave the fader all the way down on the mic, set my mic volume in obs and all I have to do is mute it via obs using a hotkey if I want to. This allowed me to use the noise gate as well as separate all the other other into my other output and control them with the mixer. Other than muting I have no need to ever change my mic volume once it is set though this works perfect for me. From what I read this is simply known as a mix-minus setup.
