I have reformatted my Dell Dimension 2400 computer and now have no sound. I have gone to the Dell website and downloaded the drivers I could. It had the Soundmax to download, which I did but it would not install correctly. I have gotten the specs on my computer and they are as follows. Motherboard= Manuf Dell Model OF5949-A01 Chipset Intel i845G REv. A1 Southbridge Intel 82801DB (ICH4) I believe that the driver for the soundmax was too old. Also, on my device manager I have the yellow question mark next to "Multimedia Audio Controller". Can anyone please help me? I really want the sound. Thanks so much.
