Microphone volume incredibly loud

Hi there, my microphone is blisteringly loud on both TS3 and TS5 - both of which have no obvious input volume control under the capture settings. It seems to be an automatic gain control-like setting as all other applications are fine, and if I hold down my PTT and make very quiet noises the volume just constantly gets louder and never reduces.

I have tried fresh installs of both TS3 and 5, and still no options or way to lower the volume of my microphone. I could change it via my windows settings however then I become very quiet in other applications such as discord - so that is not a viable fix either.

Issue also persists on a different microphone
