I was trying to tune my guitar and when I increased the microphone input volume, I went into the sound settings, changed it, and it worked.

In the connector options list, analog microphone/microphone one was selected. For some reason, I changed it to another option (analog line-in), and seeing that it didn't work (obviously, the laptop microphone was the only one "plugged-in"), I tried to change it back.

But when I did that, the connector option hopped automatically to something that isn't a microphone, line-in, input or analog video, making it undetectable.

Example: I choose Analog Video. I change input volume, it stays.
I choose Microphone. When I try to change input volume, it hops to Analog Video.

Can this error be fixed somehow?
