I recently upgraded my entire pc to a new motherboard, new vid card and a new quad core i7 cpu, everything on JA worked fine on my crappy dual core machine, now whenever i start JA the sound is distorted the only way i get the videos to play sound properly now is if i use the EAX audio and my sound card is an onboard VIA HD so not sure if its the sound card or what, my last sound card was a realtek HD and worked fine NVM i fixed it, the issue was hardware acceleration had to be disabled for some odd reason. Source: "Known Halo problem with Audigy 2 in WinXP. Turn off audio hardware acceleration. Bingo ---- problem fixed. Hardly any difference in video performance on a fast machine. New WinXP Audigy 2 drivers have just been released. Try them for all your problems and see if there is any improvement.
I don't have JA, but your problems are more likely to be driver/game conflicts than interrupt. Try experimenting with audio settings in JA ( even to the extent of turning audio off if you can ) and see if there is any improvement.
