Part 1: The Anatomy of the A220 (The Original Circuit)
Before we discuss the patch, we need the original. The "A220" is not a single chip but a reference design built around the Creative Vibra16 (CT2505, CT2800) or the CQM (Crystal Semiconductor) chipset. The core components include: Creative A220 Go to product viewer dialog for this item
