Believe me or not - five hours I'm trying to find drivers for IBM motherboard, chipset i845G.
Multimedia Audio Controller is yellowed in Device Manager (XP SP3).
Any help ?
get your chipset drivers directly from intel.com. the difference between the 845 the 845e and the 845g are slight improvments over hardware functionality. the 845e adds usb 2.0 support and pentium 4 533mhz FSB speed support. the 845 g adds the same as the 845e but also adds a 3d ghraphics controller and access to the south bridge enabling 6 onboard usb 2.0 ports. The driver for your chipset will most likely not fix your audio issue. you will need to find the manufacture of the audio chipset and get drivers from their site directly.
Is this a virtual machine or a normal install?
