Like I say, it is realtek hardware, but its modified by the board manufacture and why it has there logo and not realtek's logo. jacking around to get the mic to work on that old giga board. One off the top of my mind is when you open the manager at the bottom the real realtek will show realtek the motherboard branded realtek will have the motherboards brand name where realtek would be normallyĪs you see one is the gigiabyte realtek sound the other is a true all realtek sound by realtekĪll depends on how asus set there's up or how giga or who ever set there's up to work with there own way of doing things of features added over realtek's i'll try to post that if I did it up to show the difference I had screen shots showing that how the say gigabyte realtek was not the realtek. Ya some brands like gigabyte us e there own realtek sound that's not the real realtek so to say I had a giga board and learned this and funny thing it was over the mic not working plug and play kinda as your getting - it will work but you have to go in a set it up once you do it should work from then on unless you change it back to default
