Well it could be because of your headphones or your computer could be using the wrong output it depends.
Check that you are using the correct socket. Plugging external headphones or speakers into the socket, should switch the internal speakers off. This isn't happening, so something is fundamentally wrong.
Consult your users manual. It could be under software control in your sound settings.
Your laptop will use full audio quality if you turn up the volume 100% and change your settings to high volume.
umm duhh ok its simple go outside and catch a bird, than set the bird on your laptop and keep it there until it poops.when its done pooping on your laptop let it free outside, wait one hour and than turn the volume from mute to on and it should work, this will only work if you let the bird poop on your laptop. good luck..:) my laptop is coverd in bird poop so it rely does work good!
There is an audio-out plug next to the USB plugs. Headphones and in-ear headphones can be plugged in there. Volume can be controlled by the Mac volume control, or if present, volume control on the headphone wire. Be sure volume is not too loud when headphones or in-ear headphones are used. Excessive volume can damage hearing ability.
A good standard procedure for checking a possible hardware failure of this nature: First test the computer and the peripheral (headphones in this case). Plug another set of headphones or a speaker into the same jack you plugged the headphones into. Next, plug the headphones into another computer or mp3 player. This will help determine if it's one or the other that is faulty. Check ALL your volume controls. In Windows, there are multiple volume options. In your system tray, there is a speaker icon you can right-click on and select "volume options." Make sure you don't have something muted there. If you put your headphones into another computer and get sound, but you try a pair of headphones in your computer and nothign works you may have a faulty jack. Get a pair of phones you know work for certain, plug them into the computer. Do you get any hissing or intereference? If so, it is likely the computer. Try very gently wiggling the part of the headphones that plugs into the jack around while it's plugged in. Do you get static or popping sounds? It is likely the jack in need of repair if you do.
Check that the device is producing sound - what are the headphones plugged into? Is the volume on the device turned up. Is there a sound control panel? Unplug them and see if it is working. if necessary, borrow headphones from someone else. Try your headphones in another device. If they still don't work then they are broken and you need to replace them.
Because when you use the headphones and turn the volume up, then take the headphones out, the iPod stores what the volume was when the headphones were in, so next time you plug the headphones in, it goes back to that same volume.
You have holes - sockets - at the side or at the front of your laptop and you simply plug the headphones in where there is a picture of some headphones. Theres no neeed to install them, well you cant, you just plug them in and most of the time the socket you need to plug it into is the green one. Then you can listen and unless the volume is down, pretty much all headphones are compatible with everything!
If your volume isn't working on your computer, make sure you have the speakers plugged in. If that doesn't fix the problem, go to the bottom left of your computer screen and click on the speaker icon. You may have the volume turned off.
You plug in your headphones and turn up their volume as well as your speakers volume.
Make sure you are plugging it into the correct jack.
Make sure it is plugged into the correct jack (if an analog microphone) and that it is not muted in the Volume control.
Check out your Volume Control. The WAVE balance should be placed at the middle so that both sides of your earphones would work.
