<p dir="ltr">Hello,<br>
Is there a config option to disable the automatic microphone gain adjustments? I am referring to the case where the recording section in alsamixer has a microphone boost option that can be adjusted.<br>
When voip applications are used, particularly with echo-cancel, this slider is automatically adjusted, sometimes causing very loud background noise.<br>
This can be disabled manually if i edit the corresponding conf files in /usr/share/pulse/alsa-mixer/paths/ (Debian) and i set the volume option from merge to zero for the boost control then restart pulseaudio. But these changes are overwritten on every update.</p>
<p dir="ltr">Is there a method of achieving this without editing those files, preferably an option in the pulseaudio's own configuration?</p>
