Hi I am trying to fix my cousins laptop for her. It is a Compaq Presario V6500 running Windows Vista Home Premium 32-Bit.

The problem is that no sound is coming through the speakers. When I check the sound manager its just says "No audio devices are installed.". There are two sound programs that I can see are installed they are Realtek High Definition Audio and Conexant SmartAudio. I tried updating the Realtek driver and nothing changed. I then tried to update the Conexant driver but it just gives an error message along the lines of "cannot find device for driver" or when trying to open up the program, an error message "Could not find Conexant audio device, application cannot run properly." is displayed.

The only time you ever hear a sound is when an error message appears on screen and its a loud short BEEP. For example when uninstalling programs when the error message appears saying "are you sure you want to uninstall this program" you hear this BEEP upon pressing the OK button or trying to open up the SmartAudio program you also hear the BEEP.

Can anyone help with this problem.

All help appreciated,

Thanks, Christopher (Wooster)

Here is the link to the drivers that you need.

Below is my canned speach reguarding sound issues.

First open your device Manager and uninstall your audio driver and reboot.
Type devmgmt.msc in your run box this will open device manager find your audio device right click it then uninstall. Reboot your machine.

Try this program to get an update for your audio driver.
DriverMax - free driver download program for Windows XP & Vista
You need to register the program in the link above and you get two free drivers in a 24 hour period.

Also take a look at the links below.

Hit start button at lower left hand corner of the screen.Then in the run box type services.msc. Look for windows audio/anything to do with audio and make sure the startup type is set to automatic. To do this,right click selected service select properties then change the startup type to automatic then left click apply.You will need to reboot your machine for the changes to take effect.
