Having played RC v3 without background aircraft sound for three months, I finally saved sufficient money from my red packet to buy a new sound card. I would like to discard my SB vibra 128 for a new one. Which one is sure to work with RC v3 without any sound problem ?

Any new SoundBlaster will work: Live!, Live! Value, Live! 5.1, Audigy.Also, almost all sound cards today have multi-channel sound, so pretty mucb anything should work. Since SB's are the most popular, that's what I'd suggest. If you do choose another brand, make sure it has multi-challen sound (can play multiple simultaneous wavs).
