To connect a music player or other audio device to your laptop

If your laptop has a line-in jack, follow the instructions above for connecting a music player to a desktop computer. But to connect a music player or other audio device to most laptops, you'll have to plug it into a microphone jack. To do so, follow these steps:

Click to open Sound.

Click the Recording tab, click Microphone, and then click Properties.

Click the Listen tab, click the Listen to this device check box, and then click Apply.

Click the Levels tab and make sure the Mute button looks like this . If the button looks like this , click it to turn on sound for this connection, and then click Apply.

Play some music or other sounds on your device to test the volume coming through your computer speakers. Select the slider under Microphone, drag it right or left to increase or decrease the volume of your audio device, and then click OK. You might also want to adjust the volume on your device.

Note
If you hear noise coming out of your speakers, try reducing the volume on both the music player and in the Levels tab. The microphone jack is designed to receive sound from a microphone, which is different than sound coming from a music player
