Re: DRIVER NEEDED: Realtek Realtek ALC880(D) @ Intel 82801FB ICH6 - High Definition Audio Controller [B-1] PCI (Windows XP Home) [PCI / ISA]
With the info (or lack of) provided, all I can suggest is to visit the Realtek website:
If you want further help, please provide the following:
1: for desktop or notebook?
2: PC brand and model?
3: If this device is mounted on a retail motherboard, please provide the mb brand, model, and/or bios id string.
