[comp.sys.ibm.pc.hardware] Soundblaster Interference Problem

opr_fowler@mcis2.enet.dec.com (John Fowler) (05/29/91)

I have a Sound Blaster which is connected to an external R/S
amplifier (20-40watt?) and then to a set of 60 watt speakers.

My problem is that I get alot of electrical interference in
the form of hissing/whining and crackling noise which gets
very annoying after a while.

I have tried to ground everything the best I can and
sheild the video display cable also but it helps very little.

I would like to eliminate this background noise when I'm not
using the sound blaster so that I can leave the amp on all
the time without having to listen to my computer computing.

Any help or info would be appreciated.

TIA,
John Fowler

A little whining or beeping is normal, especially during HD
activity.  I noticed this on my machine, so when I was talking
with Creative Labs I asked them about it.  They said that it
happens on certain machines, though it may be much worse
on some than on others.

This phenomenon accounts for the PARROT program's initial
interference check; i.e., you have to set the level of interference
to screen out as much noise as you can for your particular pc.

Here are two things which might help:

1) Turn the volume down on your sb card and use your external
   amplifier to compensate.  

2) Move the sb card to a slot further away from your power supply
   and your hard drive.
