HP Pro 3125 MT - Windows 7 Enterprise 64. Sound is not working.

Question

HP Pro 3125 MT - Windows 7 64 bit. I've installed the audio driver SP51083 as suggested by HP (here).
As soon as I installed them the sound is not working anymore. The sound card is seen by the control panel, and everything seems to be correct (the system even detect when a jack plug is connected or disconnected to the audio card), but no sound come out from the speakers. I just hear a soft buzz.
I couldn't rollback, so I tried to uninstall drivers and install Realtek ones (here)
Same result.
Note: speakers are working ( if I plug them to another computer they works witout problems). However even headphones are recognized by the Realtek panel, when connected, but the output is, also in this case, always a buzz.
Any idea? Thank you.

Hi:
Did you try uninstalling the entire audio device?
Right click on the device and select uninstall, and check the box that says uninstall drivers. reboot and see what happens.
Then if the audio doesn't automatically install,  you can try manually reinstalling the driver by browing to the installation folder that was created when you extracted the driver.
Click on the audio driver in the device manager. Click on the driver tab. Click on update driver and browse to the driver folder that was created. The HP driver would be found in C:\SWSETUP\sp51083.
If none of that works, maybe someone else has another idea you can try.
When I am confounded by issues like this, I reinstall the OS, applications notwithstanding.
I look at it this way. I can spend hours getting nowhere, or I can bite the bullet and get my PC back up and running. Then I know not to install a program or driver the next time that killed a function of my PC.
