Recording Volume Mixer toolbar

I’m trying to boost the level of the audio coming for my reshow cassette to USB:USB PnP Audio Device. I slide the bar adjacent to the microphone in the mixer toolbar but the levels don’t change in the meter toolbar and on its own the mixer toolbar resets back to zero.

Confused

Windows guy here.

Neither the system nor the Audacity volume controls can be used to control the volume of a USB channel. You can amplify the signal once it is recorded.

Is this your player?
