I received a Dell Inspiron 1150 for free recently but the audio does not work. It will not let me go to the sound control and when a put a cd in the drive it says an audio driver is not installed. I went to ny sounds folder in the control panel and a sound driver is not in there so i restarted my computer and find out its a SigmaTel 9750. I tried downloading the driver off a couple different sites but it will always give me an error at the end of the download that there wasnt an object or my system os was not right. I have a windows xp pro so I dont know what the deal is. Can someone please help
