Diagnose & Fix a Crackling of laptop sub-woofer Sound in Linux – Ubuntu, Mint Linux, fedora

The woofer is set to max with no way to lower it. Sound crackles

The problem due to Volume adjustment doesn’t work properly & lfe volume always become 100%.

So edit he following file :

/usr/share/pulseaudio/alsa-mixer/paths/analog-output.conf.common

open the file with root / administrative power using any text editor.

vi /usr/share/pulseaudio/alsa-mixer/paths/analog-output.conf

in the LFE section –> [Element LFE]

change “volume = ignore”
