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.Identifying microphone and headphone connectors on notebook PCs
There are two types of headphone connectors on HP computers:
- The first type supports only sound to the headphones.
- The second type supports both sound to the headphones and the use of a microphone.
The connectors are marked with symbols next to them.
Figure : Example of microphone and headphone connectors on notebook PCs
Headphones use either a four-point plug or a three-point plug. Each of these plugs perform different audio functions. Make sure the plug is connected to the correct computer connector, as described below.
- Connectors on the computer marked with a headset with a microphone, , support sound and the use of a microphone when used with a headset with a four-pin plug and a microphone.
Figure : Four-pin plug
To use the microphone and hear sound from the computer, the four-pin plug and four-pin connector must be used.
Using a four-pin plug that is capable of supporting a microphone in a three-pin connector allows sound to be heard, but the microphone does not work because the computer's three-pin connector does not support a microphone.
- Connectors on the computer marked with a headset only, , support output sound only and work with a standard three-pin headphone or a four-pin headphone, for sound only.
