cannot use the program - recording level slider stuck at 11

I saw this topic elsewhere, but there were no answers provided related to the problem. latest ubuntu linux os. There is no way to adjust the recording input levels. there is a slider. it does nothing. Any suggestions that involve the recording level slider function - i don’t need to be told to adjust my microphone volume outside of the program.

OK, I won’t tell you, I’ll just say that you’re right - that’s what you do.
