No sound drivers working on old Toshiba laptop

[smc_Eclipse]

Hi, I have this old Toshiba laptop with Windows XP, I want to set it up just so I can install some early 2000s games (the laptop is from sometime after 2006?) and I have installed all the drivers but the sound card. I would install Vista, but I don't have any more DDR2 laptop memory, and I feel like being time-period accurate. I've gone around on Google trying to find the driver but none are working, and the Toshiba page doesn't exist anymore. Any ideas on what I can do or where I should be looking? 

 

Laptop: Toshiba Satellite Pro L20 PSL2YA-00K00J

Sound Card: PCI\VEN_1002&DEV_4370&SUBSYS_FF311179 

 

I feel the subsys could be important to this as all the drivers I've found only match other subsys but same vendor and device, editing the .inf files doesn't seem to work.
