Cannot adjust recording slider

I’m a bit confused about the recording level slider. It seems to be set at max and cannot slide it down. I am recording from various sources through the Windows WASAPI I am not using the Mic option. Anyone clear this up?
Thanks Much!

Audacity does that when it thinks its input system is already digital. It does that with USB microphones for one example. You’re supposed to adjust the volume with the microphone, interface or mixer controls.

Once you overload a digital sound channel, it’s already too late. There is no fixing it by turning it down later.

Thanks…so it acts to set a maximum recording level. But it is not a ‘limiter.’ Correct?
