Audio pops on LAN access

[Entropy1024]

I have my main, workhorse, PC with a Creative Sound Blaster Audigy 2
card installed. It works fine until There is any access over my LAN to
and from this main machine.

I can be playing a sound file on this main PC and it's fine, but if I
then save a document to a drive on another machine on my LAN I get
horrible audio pops till the remote disk access stops.


I have tried moving the sound card to other slots in the motherboard
but it's not solved the problem.


Can anyone suggest what may be causing this problem and is there a fix?



Many thanks

Have you downloaded & installed the latest Firmware update for the
Audigy ? Might also check for a driver update. Creative makes good
hardware, but they still need to work on the software side of things.

This is almost certainly a PCI bus issue. Depending on what chipset you
are using there are a number of BIOS tweaks to try. This is really a
hardware problem and has nothing to do with Windows.

When you say 'PCI bus issue' can you explain a bit more please?

I'm wondering if the LAN card & Audio card may share an interrupt or
something. Is this what you are suggesting?

Many thanks for the reply.

PS
I have a IC7-G Motherboard and running Windows XP SP2.

When two devices transfer stuff over the PCI bus at the same time they
can get in each others way. This most often happens when the mainboard
or a device are stupid and don't follow the PCI specs.

Creative sound cards are well known for their crappy PCI interface.
Intel mainboards generally have a good PCI bus.

Maybe a different LAN card will fix this. Maybe the mainboard or the
sound card can be tweaked. The key phrase is "PCI latency".

Maybe this helps:

No. LAN and sound card can share an INT with no problems.
