Why isn't my mic working in my headset not working on my Apple PC? It is a RUNMUS K8.

either your headset is defective or your settings is defective.

Explanation:

Your combined headphone/mic plug probably has four 'bands' including the tip.

Does your MacBook have one or two audio mini-jack inputs?

If it has one jack, you should be OK, but your headset mic could be defective. Have you tried a different combined mic/headset?

Older MacBooks have two separate jacks for audio input and headphones. 'Line in' audio expects an amplified audio source as input, such as a microphone attached to an external amplifier, or an iPod output through a stereo cable with a mini-plug on each end. Your headphone mic is probably not amplified.

This screen capture shows a (blue dot) peak audio indicator with a (mono) amplified mic as input.

If you have an unamplified mic, you likely won't get ANY sound indication from Line In, even tapping directly on the mic.

yes we can change both the color of the value of a cell as well as background color of a cell at the same time .

as we know that excel sheet consists of columns and rows.

and intersection of column and row is called cell.

we can change color of the cell and background of the cell at the same time.

hence the statement that

can a person change color of the cell and background of the cell at the same time is true.
