    Before I can give you a straight answer I would like for you to do a few things for me first.

    If you know what your sound card is called, please tell me now.
    Go to the Start Menu > Run
    Type in devmgmt.msc

    Once your in the device manager, look to see if any unknown devices appear. If the device is unknown in the device manager, it should have a big question mark, over that there should then be a yellow circle with an exclamation mark. Unknown Devices

    Even if you found some unknown devices, look under Sound, Video, and Game Controllers. Tell me what you see.

    Then go to;
    Start Menu > Control Panel > Sounds and make sure everything is set correctly.

Ok. Well then all you need is to update your drivers. There is software available to do this for you, but you will have to pay. This makes life easier, but its not necessary. If you choose this option, I recommend uni blue driver scanner.

You can also use the device manager to update your drivers. Follow the steps provided before to reach the device manger but this time, right click on the unidentified devices and select update drivers. A new window will open prompting you to either look for drivers online or in a chosen directory, search online. In my own experiance, I've noticed this methoded usually doesn't give the best results.

If you can find out exactly what the unidentified devices are then you can search for the drivers online at the manufacturers website.

If this is a company distributed laptop or desktop (e.g. HP, DELL, Sony), well, then your in luck, you won't have to know the names of the devices, as long as you didn't change any hardware in your computer.

For example, I am using a Compaq Presario F761US notebook pc.
I would go to > Support & Drivers > Download drivers and software (and firmware) > and search for my product. Compaq Presario F761US. Then select my operating system, Vista.

This is the result.

As you may have noticed, the drivers for all of the hardware that come with this pc appears on the page.

You can do the same for your laptop or desktop or if you provide the Manufacturer and the Model Number, I can provide links to the drivers you need for you.

A note on the recovery disk, that suggestion will work as well if you have not altered the hardware, but it will restore everything to the factory default, thus you will loose all of your data. Use this option if you don't mind loosing data and if your having performance trouble.

    My apologies for not noticing your model and number in the help topic title.

    The following are the drivers for your Dell Latitude D505

    SIGMATEL STAC 9750 AC97 audio
    Intel (R) PRO/Wireless 2200BG Network Connection ethernet
    Intel Extreme Graphics 855 GM video

    Download and install these drivers. if I made a mistake as to which hardware you have, you will get an error message durring installation saying that the device could not be found.

    This should help you with any errors your having and it should also help your pc run faster. The setup wizard once started should take care of anything.

The sound on my firefox browser is low but when I listen to Window media player, it is very loud.

Try following solutions, if it works for you

To switch between speakers and headphones on Firefox,
make sure your headphones are plugged in first,
Right click on volume on the bottom right corner of your screen,
Then select Volume Mixer,
then double click on System sounds,
Click on the playback tab,
then you could switch between speakers or headphones, just select one and click "set default" and OK
only sounds in firefox will play in the headphones,
and windows media player will play on the speakers

You could leave your windows media player to play on the speakers while you listen to firefox videos in the headphones

If you want the media music player to play in your headphones also;
You have to change it in the media player program,
go to options on the media player, then look for playback devices, there should be 2 options speakers and headphones,
just pick one

I usually set the firefox audio to my headphones,
and a media player to the speakers

Please rate & vote if you like solution...

Without mother board cd ,how can we start music in laptop

I think you're talking about a CD player in the computer, right? You can download and play mp3 music files on software on your computer. Windows Media Player will do this. You can download free music from a site called Azureus Vuse. After you download the music files to your computer, you can click on them and they will come up in Windows Media Player and play. Good luck, hope I answered your question.

When I Play Music through Winamp/Media Player it

That is unusual - pressing in case should not effect play - not like a tape drive would.
Are you playing from CD or Hard-drive?
If Cd - try copy music to hard-drive and see how it plays - if ok - then something may be rubbing on CD in CD-Player? But that would give read errors. Have to remove CD Player and clean it.

No audio file will play on WMP, no dvd or audio disk will play...

Windows Media Player cannot play several files in the playlist. This might be caused by one or more problems.
To find information about the specific problems, click the Now Playing tab, and then click the blue or red icon next to each file in the List pane.
In some cases, you might encounter this error message if there is a problem with your sound device, such as a sound card or sound controller. For example:
  • Your sound device requires an updated driver. To determine if an updated driver is available, see Windows Update or see the sound device manufacturer's Web site.
  • Your sound device is not functioning properly. To troubleshoot the problem, see Windows Help and Support or refer to your sound device's documentation.
  • You do not have a sound device installed on your computer. Install a sound device, and then try to play the file again

HP Pavillion not reading audio CD

It is possible that this is a drive issue, I've seen drives that one of the optical reader device has gone out, but generally it'e the DVD reader and will only read CD's. It's very rare that the CD reader goes and the DVD reader works. Before you replace drive, if it's only music CD's (you didn't mention program CD's), then update your media player. If it still won't play, then unistall the media player and completely reload it. At this point you can replacse the drive.
