Hmm, your IRQ isn't changing? I think XP is overriding your BIOS IRQs.
Try uninstalling the sound card and enable your onboard sound once again. List your IRQs again so we can see if your onboard is also IRQ16.
Also, when flying online, right click on the map and select I think it's "net status". Does your variance spike when you press the "T" key? Does your connection show any delay in the network? Another possibility is it may have something to do with your network card...
Wing, I am thinking it's either
1)IRQ conflict
2)network card issue
3)or something to do with your Microsoft UAA Bus Driver for High Definition Audio.
Will know once you gather more info.
Sorry to bother you but also check to see if your preferred recording device and tell us what's it's selected to.
BTW, good luck in FSO.
I was able to get the sound card on IRQ18 by moving some fans around.
