sound and video using same IRQ

[sillyputty]

I have Sisoft's Sandra and was looking through the IRQs in system
resources. Both Envy24 Family Services Controller (audio) and the
video card (nVidia GeFore 7600 GT) are using IRQ 16. Will this causes
problems? I've been having audio problems. Thx.

When do the sound problems happen.

Are you using onboard sound or an add-in card?

Sharing IRQs can cause problems, but often trying to assign specific IRQs
causes a lot more problems. I don't think it is a common problem with todays
comps. I think if a PCI card won't share and IRQ happily it isn't fully
compliant of the PCI 2.0 standards, but don't quote me on that ;-)

Some games specify hardware acceleration by default for the sound which can
cause problems.

If you can re-create the problem, you might running DXdiag, (from "run" on
the start menu or command prompt), and under the sound tab lowering hardware
acceleration there to see if it makes a difference.

BTW System Information under System Tools menu provides this hardware
information also.

I was getting no sound when playing DVDs (other audio worked fine),
but I think I solved it. I had recently reinstalled XP and needed to
reinstall the decoders. Now getting DVD audio in VLC (haven't tried
the other players yet). What still has me stumped is I can't install
new drivers for the sound card. Keep getting 'access denied.' Doing
some research it could be due to another device using the card, but
haven't done any further trouble-shooting yet.

Ran DXdiag with no errors.

I know. I'm a beta tester for SiSoft.
