I don't know what's going on with my audio stack

Yesterday I connected my microphone because I needed to use Discord and chat with my friends. I discovered a strange behavior. No matter what I do there is a strange noise coming from my microphone (I guess?). The thing I can hear the noise even if my microphone is not connected and pavucontrol seems to confirm this.
Today I was able do make a recordig of the issue, here: Audio bug Garuda - YouTube

Let me know what logs do you need, I'll gladly provide them to you

Did it not alert you to include this when you made this post?

Sure, but people do not like to read, my picture about nobody understand (so I moved it away).
And for a video, I have no time :wink:

If your microphone is not connected then the noise can't be coming from the microphone. It could, however, be electrical noise that is being amplified (so check your audio gain settings).

What other changes did you make to your audio setup when you were configuring it for Discord?

So, how close is your cell phone to your setup?

I made no changes to my audio setup
I haven't been using my microphone in a long time
The gain is 100%, if I lower it the noise seems to be gone but my voice too lol
I think it should not be there to begin with

Pretty far and noise is still there

Have you searched extensively for terms such as:

Audio noise Linux
Audio static Linux

I'm sure there must be many hits regarding this issue, as I have researched it in the past when I had similar issues. Sometimes a kernel update would solve the issue, or simply test other kernels for some improvement.

So, I found this Wiki but I don't know how to make such changes since Garuda uses pipewire by default

https://wiki.archlinux.org/title/PipeWire

I created a new config file following the "Microphone is not detected" section, which looks like this:

context.objects = [
    { factory = adapter
        args = {
            factory.name           = api.alsa.pcm.source
            node.name              = "microphone"
            node.description       = "Undetected Microphone"
            media.class            = "Audio/Source"
            api.alsa.path          = "hw:1,0"
            audio.format           = "S16LE"
            audio.rate             = 48000
    }
]

The issue is still there. To rule out it is a hardware problem, I tested it on Windows too, and it works perfectly
Shall I try pulseaudio, an older kernel peraphs?

If you remove this device, do you still experience the issue?

Yes, I do
Actually, since it is wireless, it is one of the few devices that work flawlessly. But since it's summer and I'd like to avoid using those big headphones, it would be great if this could be sorted out
