Cancel noise from headphone (linux).md

This cancels noise using PulseAudio

Step 1:

Add the following lines on /etc/pulse/default.pa if not added

load-module module-filter-heuristics
load-module module-filter-apply
load-module module-echo-cancel aec_args="analog_gain_control=0 digital_gain_control=0"

step 2:

Restart the PC or atleast PulseAudio using following command

pulseaudio -k

New sound input option will be added like echo cacelled with ...., it can be checked from Sound > Input > Device

Step 3: (optional)

For some cases PulseAudio need to started after each reboot, so the restart command can be added in the startup command
