how to fix microphone sound problem[Linux microphone parasite echo)

in #microphone7 years ago

Hi my friend said that during the conversation it was the sound of echo and noise.I solved the problem like this.

  • Open Terminal (ctrl + alt + t)
  • write alsamixer and press enter
  • The screen looks like the following

alsamixer-mix

you can change your sound settings with the arrow keys and you can adjust your advanced settings by moving left and right.

F4 = Shows recording devices ie microphone and its variants.
F3 = Show playback devices
F5 = Show all audio devices.
F6 = Helps you choose your sound card

If you can not see the advanced settings, lets open terminal

sudo add-apt-repository ppa:ubuntu-audio-dev
sudo apt-get update
sudo apt-get dist-upgrade

then reboot the system. After the system is turned on,

sudo nano /etc/pulse/default.pa

finding echo a line and add

load-module module-echo-cancel

Then enter the sound settings, the option will come out

cancel echo

echo cancel

resolved ;)
