echo cancellation in audio enhancements fixes that for me, if you don't have the option, try installing new audio drivers, maybe it will appear. if it doesnt you can try using the inbuilt discord echo cancellation in settings>voice & video>echo cancellation

according to the website it looks like it came with a USB adapter, if your mic is bleeding through aux, use the USB.

for whatever reason realtek in my experience fucking hates microphone line in, especially if you're doing what i think you're doing and running both audio out and audio in through one cable.

also im assuming if it came with software, the software would probably work better anyways with the USB connection as opposed to the 3.5mm

if you don't have the USB, USB soundcards are like 20 USD on amazon, but given that the headset is like 80 bucks on its own, maybe its better to just live with it and try using discord's baked in stuff

I already have echo cancellation enabled in audio enhancements and also the one in discord. I downloaded the new driver anyway. Once I have someone to test i will try again, maybe a new driver will just fix it.

It didnt come with a usb adapter, you could choose either usb or aux and I chose the aux one.

There is one cable going from the headset that splits at the end into 2.

There is no software for this, only the usb version has software afaik.

i try to not buy anything new since i already bought 10 billion things. Maybe I will give this a try if nothing else works.

one thing you could try if the echo cancellation isn't working is to set your microphone sample rate to the same one your headphones are using, so if your headphones use 48000hz, you'd make your microphone also use 48000hz, atleast on my setup this was necessary to make it work

If you're using 2 separate cables for the headset, are you using the front panel inputs or is it going in the back of your pc?
Some front panels can be fucking awful

Idk how valid this is nowadays but I remember 10+ years ago, me and a bunch of other people had the same issue and disabling stereo mix in your recording devices fixed it. Worth a shot since it takes 2 seconds to fix

everyone in this thread is stupid just turn down ur volume

Let's apply some logic here: Since it's aux, not USB, the physical mute button should physically disconnect the mic.
So the signal really shouldn't be coming from the mic.
Which means either the cable is picking it up somewhere, or it's software.
Considering it happens only with some programs, it reeks of a software issue.
Though you can try unplugging the mic and see what happens. Might need a dummy plug to trick the software into thinking there's still a mic attached, depending on where the software issue happens, and if you're using the front panel it could still be the wiring between the panel and the chip that's picking things up, so I urge you to use the inputs/outputs at the back of your mobo, at least for testing, but if it still happens regardless then it's most likely software.

Any interesting audio settings/software that could have loopback enabled?

Is sample rate the same as frequency? It says my headset has a frequency of 20hz-20khz. Or how do i find it out.

Using back IO for the headphones and front IO for speakers that i sometimes use.

already tried this, see original post

I tried out some things, i can unplug the mic on the headset. When doing that my friend could still hear my audio (but it was quieter).
But when I only unplugged the mic cable, he couldnt hear himself anymore at all.

Using back IO for the headphones and front IO for speakers.
I had to mess around in the audio console for this to work, this is what advanced settings look like:

(i only have 1 front io socket idk why it says 2)

So I'm assuming you're not using the speakers currently? Does it happen when you do use them? Also, just for fun, does anything change when you unplug them?

For an actual potential fix, try setting recording device to separate.

If you mean using the speakers as audio output and using the headset mic as in, I just tried that and my friends cant hear my audio this way.

Unplugging speakers changes nothing.

This also doesnt change anything.(if you meant enabling that through the audio console)

I checked and both values already are the same.

Audio gremlins are always an absolute bitch. What I would suggest if your shit isnt working no matter what, is downloading a virtual mixer like voicemeter and hard setting output/input for stuff. But this opens up its own rabbit hole of audio bullshit. If you are familiar with some audio stuff this might be your best bet, if not it will probably just make life even more hell.

If you have an NVIDIA card you could also use Nvidia Broadcast to get rid of background noise from your mic. This will require an RTX 2060 or newer, but works very well and has a negligible impact on performance.

Check your speaker plug and see if theres 3 black bands on it? if theres 3 bands (unlikely tho cause speakers) that may be why the front panel is detecting a mic. Spotify will send audio to "correct" default output most of the time, but sometimes windows/whatever app sends output to the thing that got plugged in FIRST, which may be the issue.

If its not yay! you get to do this bs down below.
use DDU/nuke current GPU drivers. reinstall ONLY physx/gpu drivers, no GPU audio driver. remove and reInstall windows driver following the exact instructions from motherboard manufacturer, windows 10 store is terribly ass so you may need to google around to find the exact app required. If it doesnt work from the gigabyte audio panel, you may be able to disable the front panel mic in thru the realtek audio console (which should get installed throughout the previously mentioned headache).
It should work after that, and if you need it you can reinstall GPU audio drivers once you verify it does.

also Nvidia broadcast is nuts if you can use it. RTX voice (for all Geforce/Quadro/Titan GPU's) does the same thing but at a slightly higher performance impact, like 2-3% more gpu util.

Ok, this is obviously weird, since it's usually the other way around, but it's technically a solution.

Also, thanks to all the testing we know at least that the microphone cable seems to be picking up sound from the headphone cable. I've got no idea how or why this only happens with some software though.
