All microphones plugged into my work laptop seem to be suuuuuper quiet for some reason. I’ve adjusted every slider and setting I can find, but none will go more than, say, 20% up the volume indicator when I’m talking loudly, and colleagues have mentioned the lack of volume in meetings. This applies to the inbuilt mic array, a USB headset, a different headset plugged into the audio jack, and a USB condenser "podcasting" mic, so it doesn’t seem to be device specific…
