My laptop's inbuilt speaker is not working(headphones won't work either). When I view the volume control, I cannot move it from 0.
Also, I've noticed yellow ? marks against the multimedia items. Can you help please?

Got the drivers installed?

The yellow marks are 'exclamation marks' aren't they?

Did you by any chance add a language to your laptop through the control panel, or maybe you formatted recently?

------

You could always backup any recent important files that you have updated/created since the problem and use a system restore to a point before the problem occured.
That is unless you formatted.

Yes I have reformatted recently due to my inadvertently erasing some system files. How do I tell if the drivers are installed?

Go to Control Panel

Then Click on System

Click on the Hardware Tab

Then Click On Device Manager

Go down to 'Sound, Video and game controllers'

If you have the drivers installed, there should be an option in there called something like Legacy Drivers, or Realtek AC'97.

Seeing as you did format your computer it is most likely that you haven't installed the drivers.

You might want to check other options in the Device Manager to see if you have some of your other drivers installed. The drivers can be downloaded off the internet on various sites, Microsoft. Usually and most likely you will find that your drivers disc's which come with the computers are in their separate cases with your Vista or Windows XP disc.

Hope I could help out a bit - If you need more assistance I'll see what i can do.

I looked in the Device Manager and under the sound game and video controllers, there are 5 loud speaker icons including legacy audio drivers. Does this mean they are installed and if so, why does the speaker system not work?

Time to do some checking.
Start Menu/Control Panel/Sounds and Audio Devices

Audio Tab-make sure your sound device is listed as the default.
Then under sound playback, click Volume.

Play Control will open up, where you will see several panels.
In the Play Control Panel, click on Advanced.

If 1 Digital Output is checked, uncheck it.

If it's unchecked, check it.

If you don't see Advanced in the Play Control Panel, click on Options/Advanced Controls.
Put a checkmark by everything you see listed, then look again.

After you do this, see if you have sound.

I followed your instructions and when I clicked the Audio tab, under Default Device it read "no playback devices" and the volume control is unclickable.

What you describe makes me think the audio drivers are not installed.

Have you checked Windows/Microsoft updates to see if there is an audio driver you need to install?
It would be listed under Hardware Updates.

2 more things for you to check.

1) Device Manager. Is there a listing for Other devices? If so, look there to see if there is anything related to audio and sound.

2) Is your sound enabled in Bios? Reboot your computer, boot into bios, dig around in there to find anything related to audio. (In mine, it's listed under Integrated Peripherals, where I see AC97 Audio.) If you find it, and it's disabled, enable it. Save the change and exit bios.

I checked for Microsoft hardware updates but there weren't any. I also looked in the Device Manager and found the following under
"other devices"


Multimedia audio controller

Network Controller

PCI Simple Communications Controller

Video Controller(VGA compatible

All of the above are marked in yellow with an exclamation point.

I went into bios and searched but really don't know what to look for. I couldn't find anything connected with sound/audio. Is there a generic heading under which such items might be listed?

There are several different bios systems, so it's impossible to say where to look for the setting on your computer. I'm totally out of ideas at this point-if I think of anything else, I'll post it. And if you get this solved, please let us know how.

Please post what Bios system your computer uses. Maybe someone with the same system can point you in the right direction. If you don't know which one it is, run Belarc Advisor, it will tell you.

Been thinking about Multimedia Audio Controller under Other Devices-which shows things your computer has but drivers are not installed for them. You could try installing the driver for the controller.
Right click on multimedia audio controller. Update driver. Choose No, not this time/Next.

You will be asked whether you want to install automatically or from a specific location. Try automatic. If that doesn't work, you can follow the steps for specific location.

Success :thumbsup: I solved the problem by using the Drivers & Utilities DVD that came with my computer, to re-install the audio driver. Now I am awash with glorious sound!

Glad you got it solved. LOL, another case of the easiest, most obvious thing to do.

It WAS drivers afterall.

Goodjob.

Usually and most likely you will find that your drivers disc's which come with the computers are in their separate cases with your Vista or Windows XP disc.


Although I did tell you to try the disc.

hehe
