Hi,
I have purchased a new Hercules 9800SE All-In-Wonder video card.
However, it's interfering with my previously fine Midiman Audiophile 2496
sound card. This is a replacement for a Matrox G400. This new card
contains TV-tuner and very fast 3d graphics capability.
The sound is very reminisant of the hum and high freq. noise produced by
a old low quality TV. There's a high freq. hum there all the time which
can be attenuated by moving the mouse around the monitor. The darker the
overall display the less then noise. White Explorer windows cause it to
"scream" (in my mind anyway, even though this is all very low level
really). Scrolling an Explorer window causes a quick sound not unlike the
squeak of a chamois leather on a window.
I've tried to move the 2496 as far away from the vid card as possible,
but this has had no effect. The type of noise is making me think that
the TV-tuner could be the culprit.
Anyone else experienced this kind of problem?
What was the solution apart from ditch the card? Although if I do find
no solution to this then the new vid card must go, cos sound quality is
much more important to me.
Cheers.

Not an answer to your query, but a question for you. How good is the 2496? I
am thinking of using one to play AIFFs ripped from my CD collection as a
primary source. How would it compare with a £1000 CD player?

That's a little difficult to answer considering I've never heard a £1000
CD player. I, of course, bore in mind the price when I made the purchase.
At £150 it sounds great to me. Well, before I installed this ATI card.
Especially when listening through Sennheiser HD600's

(I'd get a
silent hi-quality PC to stick it in). Sound quality is the most important
issue to me.

I'd suggest getting one you can return, if you're not happy. Order off the
web and use the distance selling regs to return it within 7 days?
Cheers.

I've seen them. One of the attachments is called an automobile.

It also appears that it can dominate the internal buses of your computer to
the point that other important processes are interrupted.

Thanks for all that info Arny. I'll peruse it and hopefully find a
solution although mine isn't quite related to that.
Sorry, I should have been clearer. This interference is audible when
listening on heaphones when no audio is playing on the card. I'm just
listening to what was previously the silence of the card. This is now
being attenuated by whatever is on the display. Open a white explorer
window and the high frequency noise increases alarmingly. Scroll a window
and get rather strange little HF squeaks.
Otherwise audio plays perfectly. Only in quiet passages of music is this
interference audible. There are no break-ups per se in the flow of data to
the 2496.
This sounds like RF interference from the vid card being picked-up by
the 2496. I can only think that some sort of shielding of the 2496 is
going to alleviate this problem?
Cheers.
