I know this sounds stupid but when was the last time you replaced the batteries in the remote? Can you use the TV volume button to change the volume up out of mute?

I have suddenly lost the sound on my windows media player I may have touched something I dont know it has been OK all this time, it plays but there is no sound please help


It appears that accidently you have clicked on the speaker icon in windows media player which has muted the sound. Please click again on the speaker icon. The sound will come back again. If it does not then check the volume settings on the task bar. This ma have been muted. Click on it and see the volume settings. The slider should not be absolutely down. Slide it up. The sound will come back again.

I lost the sound on my lap-top.I restarted it, there is no sound. I've checked that the speakers are enabled-they are, and it is not on mute...yet, there is no sound! Help!


if your computer came with a motherboard disc the sound drivers could be on it
click start control panel administrive tools computer management device manager scroll to sound,video and game controllers you might see a yellow question mark? Right click to reinstall drivers or uninstall
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 the correct settings there
also
click start control panel sounds and audio devices select advanced there might be a tick in the mute box untick it
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
if his does not fix the problem

have you tried this 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 speakers plug/outlet is usually at the back of the computer 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
try cleaning 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

I lost the sound


FIRST OF ALL CHECK THE SOUND SYMBOL OPTION ON THE SYSTEM TRAY IF IT IS IN MUTE AND ALSO RIGHT CLICK ON THE SOUND SYMBOL TO GO TO THE MIXER TO CHECK IF ANY MUTE OPTION IS CHECKED IF EVERY THING IS OK,THEN THERE MIGHT BE A PROBLEM WITH THE SPEAKERS TO CHECK THAT INSERT A EARPHONE AND TRY TO PLAY A SONG AND SEE IF YOU CAN HEAR IT IF YES AND WITH THE EXTERNAL SPEAKERS WITHOUT THE EARPHONE IS NOT WORKING THEN THERE IS A PROBLEM WITH THE SPEAKERS.
MOST OF ALL THE SPEAKERS COULD BE IN MUTE.

Speakers are not making any sounds


ok let's try a simple test.unplug the the usb.i hope that your speaker has its own power supply.turn it on.try to touch the inputs of the speaker, you should hear humming sounds.if yes, then your speaker is ok.if the speaker is getting its power from the USB port, i suggest you should use its independent power.the USB does not have enough to supply your speakers. try also the output jacks for built-in audio of the pc, ok.

Hi I Have a V2 Premier Computer And We Just Recently Got it Fixed But We've Lost our sound. Each time i try and acess our Sound thing It Says no Audio! I Highly doubt our computer is on mute! May I please...


I am guessing "Sound thing" is the volume control in the system tray (lower right corner).

If it is saying "No audio mixer" or "No audio device selected" then either one or two possibilities come to mind.

1. The shop that fixed your computer did not install the sound card properly (or left it out).

2. The sound drivers have not been installed or got corrupted.

To see if it is the first one or the second one, we need to get to Device Manager.
For XP, right click My Computer and select properties and click the hardware tab.
For Vista go to Control panel and click the System icon.

Click the button called Device Manager and see if there is anything with a yellow highlighted exclamation point. It likely will say something about unknown hardware or device. There might even be a name on the device that is a clue that it is a sound card.

If you do not see anything like that and there is no device in the category for Sound Video and Game controllers, option one is your choice. Take it back to the shop.

If you do see something that indicates it needs a driver visit the support webpage for your computer. Here is the URL: http://www.v2premier.com/techsupport/downloads.shtml
Select your model and choose sound to search for the driver.

Once you have a speaker icon in the system tray, if you still have sound problems trouble shoot the speakers.

Make sure the speakers have electric power connected and the power light is on for at least

one speaker. Make sure the volume on the speaker control is at least half way up.

Make sure your volume in Windows is at least halfway up and not muted.

Unplug the speaker jack and re-plug it firmly into the hole you just removed it from. Test

for sound.

If no sound, unplug and try another hole of the same size on the back of the computer and

test for sound. Continue testing until you have tried every hole the jack will fit into. One of

them will very likely work.

I have lost sound on my xp home edition windows for no apparent reason. Any chance of help. Thanks


If you have lost sound on the PC there could be several reasons:
1. if you use speakers the speakers could have either become unplugged, the souns could be turned down or muted.
2. The sound card could have gone bad.
3. You could have downloaded a Microsoft update that corrupted your sound.

Do the following:
1. Check you speaker cables to make sure they are plugged in correclty if you use speakers
2. Check the sound icon by your system clock in the toolbar at the bottom of the screen. If it has a red X then this is where the issue is, if not then click it and make sure it is 'Off' mute.
3. Click start right click 'My computer' and go to device manager on theproperties tab. Make sure the driver for your speakers does not show a yellow or red indicator.

If you still have an issue then go to: startr, accessories, system tools, system restore and restore the pc to a checkpoint before the date you lost your speakers/sound.

Bougth in my 2004 Compaq; work fine; Last week tried using no sound no recording.


It's possible your volume has been muted. Look down where your clock is, if there's a small speaker icon, click it once. A menu will pop up with the volume controls, and if the "mute" box is checked all you have to do is uncheck it. If the slider is at the bottom of the box, slide it up until you have sound.

If there is no speaker icon, do this: Click Start. Click Control Panel. Double-click Sounds and Audio Devices. This will bring up the sound control, and you need to check the box beside "Place volume icon in the taskbar". Also, there's an option to mute the volume above that; uncheck the box if it's already checked. This will keep the speaker icon down by your clock so you can adjust the volume anytime.

If this doesn't solve your problem, check that your speakers are plugged into the right hole in the back of your PC (not in the microphone jack). There will be little pictures beside each of the jacks so you know which is which. And if your speakers themselves have volume knobs/buttons, make sure they're turned up.

If none of this is helping you, your sound card may have come loose or become defective, so you should have a professional inspect it and possibly replace it. But it's very, very likely that your volume is muted or your speakers are unplugged. You can try using headphones if you think your speakers may be defective!

Hope this helps!
