Hey y'all,
The current state is that sound and video are better when I first turn my
comp on, but still not right. As I get more apps going, they degrade. If I
turn off other apps, it gets better for a while, then degrades again.
I've done some troubleshooting and this is what I've found.
I have upgraded my comp from Win98SE to WindowsXP Pro and OfficeXP pro. It
all went amazingly smooth except for this a nagging sound issue.
I've done some troubleshooting and this is what I've found.
I think that I have narrowed it down to an IRQ issue. For some reason, my
AGP video card, network card, ACPI, USB Host, Modem and sound cards are ALL
on IRQ 9! And there is nothing on IRQ 2, 3, 5, 10 or 11. I tried using the
BIOS to force two PCI slots (sound and network) to IRQ 10 and 11, but
Windows still shows everything on IRQ 9. There was a slight improvement in
the sound, but I have no idea why.
I found this KB article that says that everything is on IRQ 9 by design
because 'load balancing' of hardware would be too difficult for WinXP and
there is no provision for manual settings without losing other functionality
(ACPI). Thanks, MS!

Then I found this article which says that I can change resources from the
device manager, but the box is 'grayed out' on my comp.

On the other hand, if this is how all WindowsXP computers are setup by
default, then maybe my sound problem isn't an IRQ issue at all.
All drivers were updated to the latest that I could find at the
manufacturer's websites.
The motherboard is an ASUS A7M266 with the latest BIOS flash.
2 ea. WD 40GB 7200rpm hard drives.
Iomega Zip100 internal.
LGE CD/RW/DVD combo drive
Soundcard - SoundBlasterLive Platinum 5.1
Network card - Aopen card.
Video card - ATI 9100 128MB.
Any ideas?
TIA,
Mike W.
