Try each of the following connection tips, if they apply to your situation, to correct issues involving microphone connections:
Tip 1: Connect the microphone (or the source device used for line-in) into another computer or audio device. For example, to check a microphone you can plug the microphone into a tape recorder. If the tape recorder can record sound, the microphone and cable are good. If a microphone or source device does not work with another audio device, replace it.
Tip 2: Disconnect and reconnect the plug. Even if the plug was already connected to the correct connector, reconnecting might help if there is a connection problem between the plug and socket.
Tip 3: If you are using a USB microphone, try a different USB connector. If the USB microphone came with software, make sure it is installed properly and is compatible with Windows 7.
Tip 4: Know and use the correct microphone connector on your computer when connecting the microphone to the computer.
