Hi

I have XPSP2,

My sound card is sharing IRQ 11 with my
graphics card and I believe it is slowing
down performance.

How do I assign a different IRQ to my sound card?

thanks

Daniel
 
Move the card to a different PCI slot.

I don't think I have any left,
if I swap my USB and sound cards, will
that do it?
Will it cause other problems?

thanks

This is easy to test.
Disable the sound card in device manager (or even bios)
and see if the performance gets better.

why not go into the Device Manager and change IRQ manually to one that's not
being used.

Unfortunately, XP probably will not allow you to reassign an IRQ this way
and you'll need to try swapping the cards around instead :-)

Click to expand...

Modern computers and also Windows XP are designed to operate in a
shared IRQ environment and it is quite unlikely that IRQ sharing,
where there are no conflicts being reported in Device Manager, would
have an adverse impact on overall performance.

Remove the sound card temporarily and see if the performance improves.

And when comparing performance it is important to use timed benchmark
testing utilities, as subjective measurements such as "it feels
faster" are unreliable.

Good luck

Some motherboards allow you to assign specific IRQs to you PCI slots. Just
check in Windows so as to see which IRQs are assigned to "what devices". If
you do not use the standard serial, and parallel, ports, you should disable
them (so as to reclain 3 IRQs: 3, 4 and 7) and re-use these IRQs on your PCI
slots.
