HP DV6700 - No audio

Error message is "No audio output device is installed" when you click the speaker icon on the taskbar. HP's website is a nightmare: it so needs a redesign! I've tried restarting Windows audio in services. Tried uninstalling Windows Speaker in System. Any ideas? Want to avoid a full recovery if possible.

>>> HP's website is a nightmare   <--- Agree.

Try the HP site below. There is an audio driver listed for your machine. Download the driver, uninstall the auido, restart and re-install the new driver.

Next then, try the following (in order):

First run all possible hardware diagnostics. Then:

1. System File Checker: In an admin command prompt, run SFC /SCANNOW and allow to complete. Run again of errors. Then restart.

2. With a Windows 7 DVD do a Repair Install.

3. Finally you may have to reinstall Windows 7.

Did all the above and still the same. Must be a hardware problem, I guess?

Hardware diagnostics as suggested in post http:#a38005094 will disclose a hardware problem such as bad motherboard. atayqed appeared to agree with that in post http:#a38025327
