My computer can't find my sound card

August 29, 2010 at 13:18:57
Specs: Windows Vista

Hello. I have a hp dv6646us and everything worked fine until 2 days ago for no reason. I have tried everything but my computer is not detecting a sound card. I have the speaker in the tray with the x and have tried downloading the driver for it but it's saying no sound device is detected everytime. I go into device manager and can't find the "sound, video and game controller" in the list. I go into the Add Hardware in the control panel and the drivers needed or downloaded aren't listed. It makes a loud annoying screech type sound whenever the computer wants to make a sound. I am getting overly frustrated and would truly appreciate and help. Thank you

If you have speakers connected and there is some problem with them the sound chip may not function properly if at all. Could be broken.

Boot into the BIOS (setup) screens and verify the sound is enabled in the BIOS.

Thanks for the response :)

Tried the BIOS and it seems to be setup ok.

Would a broken sound card make it so the "sound, video and game controller" section not show up in the device manager?

Thanks

Yes it could. You can get relatively decent sound cards these days for dirt cheap. It might just be worth getting a new card instead of the headache of troubleshooting a faulty onboard card

Go to Control Panel > Sound & Audio Devices, click on the Audio tab. Is there anything listed for "Sound playback"?

1. go to the HP site & download the Conexant High-Definition Audio Driver, 2008-08-05 , Version:4.36.7.60 B, 22.41M, sp40170.exe

2, once you have it, unpack it - the folder will be sp40170

3. open the folder & double click on Setup.exe

- Thanks for the advice, I will probably end up doing that if I can't figure this out soon. Thank you.

- There is nothing listed for "Sound Playback". It says "no audio devices are installed"

I tried your suggestions with the download and get an error that says "Driver Installation Failed: Could not find the device for this driver"

Still not working but thank you for your time and help.

Do you have speakers connected? Try removing them and rebooting.

"Do you have speakers connected? Try removing them and rebooting."

No. Just the internal speakers. The headphone jack does not work now either.

You have a laptop which complicates things.

Did you actually boot into the BIOS (setup) screens and look at any sound options to see if there is anything listed there?

Thanks for all the help OtheHill :)


There is no sound options listed in the BIOS.

If I can't figure it out by tomorrow morning, I'll just do a system restore and start from scratch and see if it kicks back on.
