Can't find this driver. I've d/led over 20 file from hp and I still can't get audio.

I have a Compaq C715NR, used the drivers it came with (which are vista drivers) so they are loaded but no sound coming out and under audio devices nothing shows up.

I think this is a newer chip called hermosa

HWID

HDAUDIO\FUNC_01&VEN_14F1&DEV_5051&SUBSYS_103C30D9

Only drivers that have the HWID is 4.31.2.0 found at HP under this model and also on this computer.
I've installed UAA 1.00revb from hp
KB888111
and then these drivers.

If anybody can help me that would be awesome.
