I’m new to Linux. I’ve been using EndeavourOS for three days now, and I’ve encountered a problem: when I plugged in my headset microphone, my friends started hearing the sound from the video I was watching on youtube.
welcome here at the purpilization 
first think on any aufio issues is to check playing with pavucontrol app it can resolve 90% of all common issues with audio.
Not using discord here on a daily basis but afaik it has internal audio settings too.
You can show what you have in there on teh config tab and also check droop down profiles it has for your devices. in case it is smart to disable unused audio devices too.

I was using pavucontrol to switch to the headset microphone, and there was a sound issue.
there is also alsamixer a terminal tool to check all the sliders of the audio devices
It only works when I select the microphone integrated into the laptop, but the noise is too loud and the sound quality deteriorates. I am sorry, but I do not understand what you have written. After Windows 11, it is challenging to understand the function through the terminal rather than clicking on the images.
Replying to get in the loop…
I had similar behaviour with a Teams call in Firefox Browser. Mic was muted in Teams Websession yet the other participants could hear the youtube clip playing in a different tab.
Would be good to know if you’re using KDE Plasma or a different WM/DM.
In case of KDE Plasma, there should be a audio volume widget in the panel, pretty much as you’re used to on Windows with the systems tray. That’s pavucontrol, more or less. There is also a “Configure Audio Devices…” option in the top right of the widget, that will open up KDEs system settings for sound. That should also list the currently active playback streams. And a dropdown list of available sound outputs to route the audio signal to.
From everything you wrote, the configuration is suitable, and yes, I have KDE. I already looked there and nothing was suitable.
what you say looks like it does pipe the output to the input what sounds like a bug.
Could you show the output of this:
inxi -Aaz
check also discord audio settings:
In Discord: Settings —>Voice & Video Under Input Device, ensure it’s set to your headset microphone (not “Monitor of …” or “Default”).
If you see something like “Monitor of Built-in Audio”, don’t use it. That’s your loopback device.
same could be set in pavucontrol unde config tab.. if it have anything set to “monitor of” it could cause such issue.
Disable other devices and only set your headset active (if it is usb audio device) if it is plugged with audio jacks it will use internal audio hardware ..
In Discord, it only shows the default settings and nothing else, and in the pavucontrol configuration, I have analog two-way stereo from the selection, only professional sound, which does not change anything, and the others are unavailable, it says. And please forgive me if I am being so intrusive.
can you show a screenshot of pavucontrol config tab open the profile selection dropdown?
Here’s a screenshot, but it’s in Ukrainian and I don’t know how to translate it into English for you, but I want to say that this problem isn’t happening now and everything is fine. I’m surprised that I didn’t do anything, but it worked.
open a terminal and run/start it like that:
LANG=C pavucontrol
could be you used an application that changed some piping on the audio before
changed, but the configurations remained in Ukrainian
I was feeding through the Claude neural network while waiting for you and entered a couple of commands.
yea i see the same would need to have the complete session set to english.. even in terminal rpfile naming is in the set language:
LANG=C pactl list cards
