Steve,
You might post your IRQ settings here for Skuzzy and others to look at.
And this may seem weird, but do you have your sound card in the PCI slot that is closest to your AGP slot? Somtimes that can cause problems. If it is, try moving your sound card, and any other cards, away from the PCI slot that is next to the AGP slot. For some reason Windows likes to have an empty PCI slot between the AGP and the first PCI card.
If you do move your sound card you should uninstall the sound card first in System, then move the card, otherwise you may get funky IRQ problems.
And be sure that when you have reinstalled your sound card drivers that DX9 has not by default reset you to full acceleration.
From Skuzzy's Hints and Tips in the Hardware BBS:
SOUND PROBLEMS
NOTE: With version 1.11 of Aces High or later, we do require DirectX 8.1b or later. In DXDIAG, your DirectX Version should be 4.08.01.0881 or greater. If it is not, then you need to download and install DirectX from Microsoft's WEB site.
1) Press the "Start" button from the Windows desktop
2) Select "Run" from the dialog box that pops up.
3) In the Run dialog box, type DXDIAG and press the key.
This will start the Microsoft DirectX diagnostic tool.
4) Once started, select the "Sound" tab
5) Make sure you have your hardware acceleration set to no higher than 3/4 (one notch lower than full).
6) Run the Sound diagnostics and make sure is works.
If you are still having problems:
Make sure you have the latest sound chip/board drivers for your operating system. NOTE: In some cases, such as the C-Media chip or any onboard sound chip, random lockups and lost sounds seem to be normal.
If you have interrupt conflicts/sharing with any Sound Blaster board, you will have problems, such as video graphics stutter, lost sounds, general Internet connectivity issues, or any combination of the above.
Using the "System Information" tool, you can see what interrupts are being used in your computer system. NOTE: It is safe to ignore the various "Steering" interrupts.
Also if you are having problems with voice, you might try changing your record/encode method, in the game, go to "Setup", then press the "Voice" button from the clipboard and check the "Use Wave In" option to see if that will clear his problem up.
INTERRUPTS AND YOUR COMPUTER
For gaming, it is highly desirable that each device in your system be on its own interrupt. Sometimes this means moving cards around in the PCI slots to accomplish this.
Shared interrupts will cause all types of maladies. Stuttering video, sound cut-outs, all the way to system freezes and crashes.
It is difficult to tell you how to resolve this as it depends on the BIOS, motherboard, shared device type, operating system, and many other factors.
