I am helping my sister with her system. She has a sound card in her system that has no drivers installed, and is not functioning. I have had a hard time identifying it. The FCC# revealed that a company named Anchor Electronics made it, maybe! I can see only a few real identifiing numbers, again maybe. One is AV300, or maybe ADD-027844. The later is on a sticker, it may be just a stock number. The main chip has nothing but a number on it, MK16450J. Can anyone take a bite out of this dilemna?
