Keyboard clashing with sound!

[Michael]

I'm having problems with the sound on my system. I have the following -
Windows XP Home Edition
3.02 gig Intel Pentium 4
1024 Megabytes Installed Memory
120 Gigabytes Hard Drive
NVIDIA GeForce4 Ti 4200 with AGP8X

The problem is while any audio is playing, from any program, any of the keys
that are pressed on the keyboard interfere with the sound causing it to
break up, and if I'm playing a game then game play is effected as well. The
game will pause or run very slow while any key is pressed on the keyboard.
Everything runs fine as long as I'm not using the keyboard. I've tried using
different keyboards with no luck. Could someone please advise me on how to
fix this problem.

Much Obliged

Does this problem happen with all programs, or only one game?

If it is only in the one game or program, you should contact the authors or
distributors of the game or program.

This sounds like (no pun intended), like there is a problem with the IRQ
sharing when this program is run on your system.

If you have the skills, take a look at the IRQ layout for the sound card,
and keyboard. But, it is possible that the game is also causing very long
time values for its operation in some of the shared IRQ's during its
operation. This type of thing can get fairly complex. There can also be many
factors about a particular machine, of how it is working with particular
software's. It has to do with the system installation layout with the IRQ's
and how memory and caching is managed.

I have some computers here that have 2 printer ports. On one of them, the
sound card has a shared IRQ with the LPT2 port. When I am doing a print job
on LPT2, the sound will start to break up, and at the same time, the printer
can sometimes slow down, if its buffers are full and there is sound at the
same time.

Sometimes, depending on may factors, you can force an IRQ change by deleting
a card, and then removing a card. Then restart the computer to have the card
deleted. Then you can install the card in a different socket, and re-install
its drivers back. When the computer starts up after the re-installation, it
may assign a different IRQ position for that function. But, if the
particular card has to work under a particular IRQ, then this type of remedy
will not work.

Unfortunately the keyboard IRQ would be very difficult to change. But, the
sound card IRQ may change by following the advice given here. If it does not
work, you can put things back if necessary.

Michael,

Seeing that someone already posted some advice here, I just wanted to let
you know that this group is dedicated to windows XP Embedded. you might try
microsoft.public.windowsxp.general in the future, and have more responses. I
see that you kind of peppered several newsgroups with this post, just
identifying what one of them is microsoft.public.windowsxp.embedded is for
XPE...


Best Regards,
JC

It happens with all programs. If I play a song on the Media player and try
to type this email for example I get the same problem.

This sounds like (no pun intended), like there is a problem with the IRQ
sharing when this program is run on your system.

lol none taken

If you have the skills, take a look at the IRQ layout for the sound card,

time values for its operation in some of the shared IRQ's during its

No the sound (sound is OB anyway) and the keyboard don't share the same IRQ.
But...my network adapter and sound (which are both OB) are sharing the same
IRQ. Would that make sence? Could the network adapter clash with the sound,
as I am on a home network and using an ADSL modem, which is always
connected.

I have some computers here that have 2 printer ports. On one of them, the
sound card has a shared IRQ with the LPT2 port. When I am doing a print
job
on LPT2, the sound will start to break up, and at the same time, the

particular card has to work under a particular IRQ, then this type of
remedy
will not work.

I think your right about the two devices using the same IRQ, but as their
both OB how do I go about changing one of the IRQ positions?

Unfortunately the keyboard IRQ would be very difficult to change. But, the
sound card IRQ may change by following the advice given here. If it does

Thanks very much Jerry. You've shed a lot of light on the problem. I was
starting to get a bit frustrated having been trying to solve it for the last
week!

Hi JC,

As far as I can tell, he did include it in the list ;-)
