I have Windows 7 running on my old Inspiron 8200. The performance is acceptable, better than XP, actually. However, there's no sound, because apparently there are no Vista/Win7 drivers available for the integrated CS4205 chip.
Has anyone had any success with driver for Inspiron 8200 audio?
Nevermind. The Dell WDM driver works. Just make sure to install it through Device Manager, not the install program.
