The input connector doesn't change

[Arima Begoun]

I was trying to boost the Mic Volume, I have tried different input connectors to check if it had some effect,

Now the input connector doesn't change from Line-in, I try to change it back to Microphone 1 as soon I try to adjust the volume it flips back to Line in
