My 4.1 X-Gamer that I bought about 2 years ago has served me with. I've used it on 3 different motherboards and haven't had any crackling or freezing with it.
However, my brother got a SB Live Value for his KT133A motherboard, and it totally screwed up everything. Couldn't even install XP unless the soundcard was removed.
