The model is dv6810us.
It is an HP Pavilion DV6000 but model # is dv6810us. The model number is from the tag & an hp scan also stated this as the model I have.
These are the Coprocessor hardware lds

PCI\VEN_10DE&DEV_0543&SUBSYS_30CF103C&REV_A2
PCI\VEN_10DE&DEV_0543&SUBSYS_30CF103C
PCI\VEN_10DE&DEV_0543&CC_0B4000
PCI\VEN_10DE&DEV_0543&CC_0B40

After installing Windows 8.1 Pro 64X I have no sound, no sound device is being recognized, sometimes the screen goes blank for a few seconds then comes back on with a message stating video driver stooped working and has recovered. It had sound when it was running Vista. I been going with out sound and trying trying to figure this problem out. Also there is no sound showing up under device manager.

Please Help !!!!!!!!!!!!!!!!!!!!!

It says ALTEC LANSING on the laptop where the speakers are but doesn't that just mean it has that brand of speakers correct?

On HP site it gives me 3 audio drivers to choose from if I select Vista as an operating system and 2 of the drivers are for conexant hd audio & the 3rd driver is for realtek. The Conexant drivers wouldn't install stating couldn't find device for driver but i finally got the realtek to install in compatibility mode for vista service pack 2 and I'm getting ready to restart pc like it's asking me to but I feel as though the problem isn't the audio device or driver but I could be wrong I never heard of a Coprocessor before and it's listed under Other Devices in Device Manager.
Hopefully the hardware lds above will help someone to help me find the driver for the Coprocessor because I was told it is what is causing my problems. Thank you all so much.
