What you can do is go to the control panel then click "Sound". And on the Sound window you will see the tab called "playback" click on it. Then, in the dialog below the tabs you'll see your audio device the main sound from your laptop and another one. Click on the one which you have a problem with. If its your main speaker which is built in your laptop it will be easier to fix. If its the built in one you have the prob with then click it and click the "properties" tab. Click on "levels" and set them all on 100. I think that should help. since I have a HP laptop i think the settings are different because I have the realtech builti in speakers. If you have them then after you set the levels on 100 click on enchancements and checkmark the following: Environment, Equalizer, Virtual Surround, and Loudness Equalization. I think this should help!

Hope u fix it.

The yellow ? against the sound device means the sound driver is not installed or was deleted. Reinstall the audio driver and you should get sound again. If you still get the yellow ? then the audio driver didn't install properly or the wrong driver was installed. Make sure the driver matches the version of Windows ie XP or Vista.

    It does help to know the exact make and model of your laptop as you had posted it as an ACER.

    Go to the IBM/Lenovo WEB site - support/download page and download the latest Windows XP or Vista device drivers for your model computer, Use this link :-

    You can download the various drivers and then you click on and run the variour drivers, they will then unzip and expand into a folder on C:\drivers Then install the various drivers from this folder.

Cannot import pictures to my Asus laptop from my phone or camera, why?

I assume this is a Windows computer.
Disconnect all your USB devices. Go to Computer Management/Device Manager and look at all the USB devices to see if any are flagged with a red X or yellow warning icon. If yes, right click on the ones marked that way and delete them. Close and re-open Device Manager to see if all red/yellow icons are now gone and if they are, retry plugging in your phone or camera. When disconnecting those devices, remember to use the "Safely Remove..." icon in the System Tray (just left of the Date/Time.

My pc is ibm mt-m 82121yu.device manager show its audio driver is updated but sound it doesnot sound

See your sound settings in control panel, make sure that a little speaker icon is not grey, or choose sound device from list (activated one - possibly you are still using sound from motherboard, and must swith to your sound card).

Also make sure that your device has no exclamation signs in device manager, which would mean a bad or invalid driver, go to device manager and update the driver for device if device is yellow.

I all of a sudden I have no sound period! What do I do?

Right-click My Computer, then left-click Properties\Hardware\Device Manager. Find your sound icon. Is anything listed in yellow or red. Yellow means you need a driver. Red means that's been disabled somehow. Right-click the "X"ed out icon and choose Enable. If you need a driver, then go to, then Support & Drivers, enter Model or service tag (Service tag is usually on strip of white on the bottom of the laptop), then find Audio and download the most recent driver update, then install the new driver. If you still don't have sound, then it's possible that your speakers both went bad, or your integrated sound chip went bad.

Pc working good, but no sound

If you're using Windows, go to device manager [right-click My Computer, click Manage, and click Device manager in the Computer Management Console Window], next access your Sound device and make sure it does not have any yellow exclamation [conflicting drivers] or question [missing drivers] marks. If it doesnt and you still dont have sound, you'll need to download and install audio codecs from your Computer, or sound device manufacturers website...good luck

Problem with sound after windows XP installation and realtek

Is that onboard sound device..?, it seems your sound device broken, if so you can't solve problem with installing driver, you must have PCI Sound Card to enable sound on your computer.

Volume stuck on mute

I don't think you're stuck on mute I think you're having problems with your sound card. Go to device manager; if there is a yellow or red sign on sound then right click and try reinstall driver. Let me know if you have any questions. Pls rate this solution.
