My laptop was bought with windows vista on it. I put a partition on it with windows XP. I am having a problem with my audio device on XP. My sigmatel HD audio codec is not working properly. at the moment I am getting an error message saying; “the file “stwrt.sys” on Sigmatel HD Audio Wave RT Disk is needed”. The audio still works on my vista partition so the hardware is fine. I need a driver for the hardware to work on XP and have been unsuccessful on any attempt to find it on the web. Any Help?
I would try starting the computer in XP, not Vista. Then go to Microsoft update center and have them update your driver. It should find whats missing and and give you option to download correct driver.
If by chance this is a Dell laptop, you can get the stwrt.sys driver from their site. Just do a search for it.
