I have a dc5100 sff and legacy drivers. The device manager is saying that the device is working properly but still no sound if I try to play a cd, dvd, or music from my external hardrive. Even if I go through the windows media player it gives me and error message that either don't have a sound card or another program is using it.

AS you state the "device is working properly" so it must be something else.
Try playing a music CD and if the music looks as if it is playing, it probably is and there is a mechanical problem with the headphone socket or the volume is not activated.
Check the Mixer Console by r/hand mouse click the loudspeaker icon and select Volume mixer.
Hope that fixes it

Hi, "click on this site; you may be able to download the Drivers you need" http://driversupdate.org/drivers-update-software.htm?msn=download%20drivers%20hp%20compaq%20presario%20c700t%20,%20pentium%20dual%20core%20mobile

Can you play audio files even if there's no sound with the Windows Media Player? if so some files of the sound driver is missing, you need to update the sound driver. Or if you can't play, then there's no sound driver only the codec is present without the device driver, the process is more or less the same..but before you follow these steps, put the Motherboard Driver CD on the CD Rom: Right Click on My Computer - Manage - Device Manager - Right click on the Yellow icon - Update Driver - No, Not this time - Next - Install from a list or Specific location - Next - Tick the "Include this Location in the Search - Browse - Go to the CD Rom Directory and search the Driver/Audio folder - and Select the Audio Driver folder - click OK- Next - Finish.. done..... Good luck.. Do let me know if this doesn't solve your problem, i am ready to help you..

Go to your CONTROL PANEL
then select SYSTEM
then select DEVICE MANAGER
This page will list all your computer's devices.
Locate your sound card
*a yellow triangle indicates errors*
Double click on your sound card, this will bring up another window
First tab GENERAL shows if device is working properly
Click on DRIVER to update/check on drivers, if you need drivers, it will search and locate them for you.

You may need to restart.

Hope this helps.

Hi, Did you install your sound drivers etc. If you havent done the instalation then your sound card will not work. Follow this process Right click on mycomputer, then properties Device ,manager and then check if ur sound drivers etc. are installed.

Open the Device Manager, click on the icon, which is marked with question mark, hit delete button then a prompt will pop-up then hit Yes. After a while or after Windows restart, it will prompt you that you need to install driver for a new hardware, I assume you still have the Drivers CD, which comes with your PC, dictate the PC to search driver from the CD or DVD drive. This should do the trick. if you still have further inquiries or if still this doesn't work, please post another thread.
