Can't find correct audio drivers

Hi,

I have an Intel audio device, so I downloaded different audio drivers from inter support and tried to install them, some of them tell me that the computer does not have the minimum requirements, and others installs, but after installing and rebooting, in the device manager I still see that the audio drivers are the ones that came with Windows.

I have a Windows 7 64-bit machine and this is the info I can read from Unknown Device Identifier 8.01:

Chip: Intel  Haswell HD Audio Controller

PnpID: VEN_8086&DEV_0C0C&SUBSYS_35371558&REV_06

Chip Vendor: Intel

Chip: Haswell HD Audio Controller

Please, someone that has the same specs as me and found a working driver?

Thank you.
