All right people have a bunch of really short solutions to these problems that aren't really solutions on this site. They just seem to be like yo somethings wrong with your computer. It might be your firmware. Well try this... Zap the PRAM

1. Shut Down.
2. Start up and hold cmd + opt. + p + r
3. While holding this the computer should start up and
automatically restart your computer again while still holding it.

Upon the second start it should Make a Chime and the sound should come back. If not then its not your firmware. It Might be that you threw away your built in speaker prefs. or the speaker shorted and u need a new one. To test this plug in your headphones to see if they work. If not then you have an internal software problem and you should take it to a technician. He may have to reload your system so back everything up. And be ready with the Mac start up discs that were given with the computer. Hope this helps. I'm going through the same thing right now with my G4 and am at the point where I need a tech. I may just buy a new Comp. (I love my G4 though)

Check the Mute button make sure it is not selected, also check the volume level,move the volume setting higher or to max.
Check the audio chip is OK by plugging headphones into the audio out/headphone socket.
If it is OK then most likely the speakers are faulty and they need to be replaced.

How do I diagnose and fix my laptop's sound problem? Should I just throw it out the window?


From the description you have a hardware problem possibily caused by the ipod plugged into the headphone jack of the laptop. I'am convinced the sound section on the motherboard is damaged, probably the audio output ic. But to trouble shoot the problem will require someone with a strong background in electronics, I would suggest going no further until you have estimate in hand.

How do I diagnose and fix my laptop's sound problem? Should I just throw it out the window?


which operating system

You receive an error that states: There might be a problem with your audio device

if your computer came with a motherboard disc the sound drivers could be on it

click start control panel administrative tools computer management device manager scroll to sound video and game controllers you might see a yellow question exclamation mark? ! or a red X Right click to

reinstall drivers

click start control panel sounds and audio volume advanced speakers make sure you have selected the

(appropriate speakers) also audio you will find 3 drop down lists make sure you have selected the correct speaker settings there

click start control panel sounds and audio devices select advanced there might be a tick in the mute box untick it


if his does not fix the problem

click start control panel sounds and audio devices you can adjust the volume there also select speaker

volume you can change your settings there you can also tick in the box place icon in taskbar for any

further volume control settings you will need to right click on the speaker volume icon system select adjust volume


click start control panel sounds and audio volume advanced speakers select the appropriate speakers


from the drop down list or navigate to the device manager scroll to system devices + to expand system

speaker right click properties then select use this device (enable) also you might check


the speaker plug/outlets is usually at the back of the computer or if its a laptop on the side

you will have to open up the computer to check the lead attached to the rear of the input plug make

sure the connection is good with no dust as dust causes static electricity


clean your computer of dust using a fine air blower from a compressor making VERY sure that there is

no MOISTURE in the air line specifically around the sound card and the CPU central processing unit

dust causes static to build up in a computer


hope this helps

My speaker all of a sudden stopped working, they are built into my monitor, and worked last night. what do i do?


  1. Check the volume control in windows and make sure audio was't muted
  2. Check the audio cable and ensure it is connected to the port on the system
  3. Ensure headphones are not plugged in an aux audio port as they will mute the speakers
  4. Check the audio drivers in Device manager
  5. Try a known good set of speakers (Or CD player headphones) and ensure the audio on the system if functional
  6. If all else fails, replace the speakers ($20 or less at any major department store)

Labtec LCS-2424 speakers: left speaker stopped working


I have the same problem sir, only the speaker with volume
control works. Earlier I used to twist the volume control this
way and that way to get the sound from the other speaker also.
Now the same technique doesn't work anymore.

My laptops speakers stopped working


Have you tried a pair of headphones to see if they work?
Is the sound ouput muted? (a lot of laptops have a physical button to
do this...

check to see if the laptop is muted. Also, check the
volume control to see if everything is up where it should be, including
Speaker Out.

If I've got this all straight, the only thing that it can be is an
issue with the plug on the speakers and the jack on the laptop.

Obviously the computer is putting out sound to the headphone jack as
evidenced by your ability to listen through headphones. The speakers
work on another computer. So, it has to be something specific about
the Speakers on this laptop. Plug/Jack problem is the only thing that
comes to mind.

No sound


To troubleshoot a no sound issue first you must check your device manager to make sure the audio device is installed properly.

To goto the device manager in XP:
Right click my computer>Properties > Hardware Tab > Device manager.

Look for your audio device in the list under "Sound, Video and game controllers". If it has a exclamation mark or question mark beside it you will need to download the most recent drivers from the manufacturer's website.

Next step is to goto
start>programs>accessories>entertainment>volume control
make sure that Wave nor Master Volume is not muted, and both are turned up.

Third step is to check for onboard volume control, there might be volume controls on the system hardware itself.

If you say that external speakers work and not the built in speakers, then the headphone jack that you plug the speakers into may be defective. As it is always detecting something plugged into it and never turns the internal speakers on.
