What Happened To PC Gaming Audio?

Thanks to The Adrenaline Vault for its feature discussing why computer audio has become a critically undervalued part of a PC purchase. The author indicates the worry that "computer audio is taken for granted, and that other components make the difference between high- and low-end systems", and voices concern that "most new [PC] computer games - including major releases - don't take advantage in any significant way of the capabilities of the latest generation of audio cards." He ends with the heartfelt wish: "I'm waiting for the day when I hear someone say, 'That game sounds so great, I have to buy it!' I hope people become more educated about audio so they can talk about it with the same enthusiasm that they discuss 3D video hardware acceleration or high definition plasma screens."
