Hi all, been trying to figure out why my internal laptop microphone sensitivity is so low. I found a Mic Boost
option in the capture settings of alsamixer
but this didn’t seem to change anything.
I did end up finding what I consider a partial solution on the Arch Wiki. I say partial because the sensitivity now shows 366% on the KDE Plasma UI. I’m okay with janky in the backend but is there anyway to essentially normalize to a higher input sensitivity range? Because if I want to change this 366% to something like, 330% I would need to do this via command line again since dragging the slider any amount in any direction immediately brings it down to 150% (which is too quiet).
I’m also open to any alternative solutions, something along the lines of changing what the system considers the “base” volume since as I understand, this “base volume” is what PulseAudio considers the default volume before any adjustments.
Here’s my inxi
