How do I disable my camera microphone?

Support Sound
1

Hello everyone, I want help to configure my microphone, I would appreciate any tips. So I have two microphones: the microphone of my webcam REDRAGON (which I don’t want to use), and the microphone from my headset HyperX. Everything works fine when I don’t use echo cancell and noise reduction from a tutorial that I’ve followed on the internet. If turn on my computer only with the HyperX microphone connected, it works fine with noise reduction and echo cancel, but if I turn on my computer with both microphones connected (Camera and Headset), only the camera microphone works and the microphone of Headset disappear from my configurations. So I want to block completely the microphone of REDRAGON camera, is it possible?

The tutorial that I’ve followed says to add the lines

load-module module-echo-cancel aec_args="analog_gain_control=0 digital_gain_control=0" source_name=noiseless

and

set-default-source noiseless

at the end of this text file

sudo nano /etc/pulse/default.pa

also, here are information of my machine

Hi @denielt,

I don’t have Gnome, so might be wrong.

Isn’t it as simple as muting it in the sound configuration?

just install pavucontrol and go to the “Configuration” tab at the very right and disable your webcam’s microphone by choosing “Off” from the dropdown menu.

Well, it wouldn’t solve the problem… cause muting the device would not make me able to use HyperX microphone, since when REDRAGON camera microphone is being used I can’t use any other microphone with echo cancel and noise reduction. Anyway I just found a way to block my webcam to be read as an audio device here’s the link Blacklisting your USB Webcam's built-in microphone in Linux this is exactly my problem. I’m trying to fix following this tutorial right now.

So, here’s the solution I found:

using the comand lsusb I found a list of USB devices, and which one I wanted to add to blocklist (my microphone camera)

lsusb                                                            ✔

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

After identifying the device I created a rule to add his addres in a blocklist creating a configuration file: sudo gedit /etc/udev/rules.d/90-block-webcam-sound.rules and in this file I configured my usb camera to not be read as an audio device

SUBSYSTEM=="usb", DRIVER=="snd-usb-audio", ATTRS{idVendor}=="09da", ATTRS{idProduct}=="2690", ATTR{authorized}="0"

Now the only microphone working in my computer is the HyperX microphone from headset.
