Audio Output Device Download For Windows 8.1

Input
I have an older HP Pavilion DV6810us that originally came with Vista.
After 8.1 Pro install I have no sound device or recording device detected & no sound.
Under Device manager there is a ? on the Coprocessor which I believe is what controls the sound.
There is no other audio or sound device anywhere in device manager.
I have been through several nvidea & HP drivers, tried compatibility mode for Vista etc.
The motherboard is quanta 30CF
Chipset Nvidea nforce 560
Graphics Nvidea GeForce 7150M/nforce630m
I have had several driver problems with other pc's in the past and could figure them out but not this one.
I've been without sound for 2 weeks now and refuse to run Vista.
Please help, Thank you.
