Finding manufacturer for Sound Drivers on HP Notebook

[Dan]

No sound drivers found for the hardware: "The drivers for this device are
not installed. (Code 28)
mfg: unknown
location: PCI bus 0, device 20, function 5"

The computer manufacturer has been unable to help me. They tell me the
company they OEM the hardware from no longer exists and they can't do
anything about it. I have spent hours on the phone with HP who now tells me
the need proof of purchase before they can help me. I'm 10 months into a 1
yr. warrenty, but I can't find my paperwork. Support through HP is a dead
end for me.

How do I find out who the sound device mfg is?

I'm thinking maybe Microsoft has a 32 bit driver that someone is bound to
have ported to 64bit.

Hello Dan,

After digging around on the HP site, I found Vista 32 bit drivers for that
notebook soundcard, but not 64 bit ones. It's Conexant AC-Link Audio
Driver. Conexant have to date been seemingly incapable of providing working
64 bit drivers.

Thanks! At least I know the mfg now, so you move me a step further.

I then tried the following driver, but result="failure"

Thanks for the direction!
