Hissing speakers
Hi
I bought some time ago a set of Creative P5800 speakers (5.1) and I'm really getting tired of the (almost) constant hissing they make. I've tried the usual tweakings : muting mic/line-in, nothing works. What's more, I've tried to connect my sound card to my stereo and there is no interference; my sound card is not the culprit here. Maybe there is something I overlooked, but it seems to me that these speakers are just crap, period.
If this is the case, could you guys recommend some really quiet speakers (I suppose that's a problem of EMI shielding... maybe cables)? I was thinking about hi-end Logitech ones (like the Z550), but they cost a lot and I want to make sure that they won't have the same issue.
Thanks!

First thing you should try is plugging the speaker power unit into a different outlet. If you can, try moving the whole setup to a different part of your home to test it. Lots of time speaker noise is from noisy wiring and/or spurious emissions from other equipment (sometimes belonging to neighbors if you live in an apartment complex).
You just need to turn them down. Unless it's actually interference from something. Do they hiss if you plug another audio source in to them, do they still hiss if you turn the volume all the way down? If not turn them all teh way down, then turn them up until you notice hiss, then turn them down slightly. Now just use the volume control on your PC to change the volume. Possibly mark where you have it set so that if you need more volume than this, when playing a game or soething, then turn them up too... but that would be unlikely.

Ok.
1.) Do they hiss when turned on and the input plug(s) are are disconnected from any source? If they don't hiss, it's not the speakers.
2.) If they start to his when plugged into your pc, make sure your pc is properly grounded, and that you pc speaker system is not grounded, assuming it has a 3 power pin plug as well.
I hope that helps.

I'm pretty sure they will, since they hiss even when the computer is turned off. I'm going to try that anyway.tgdrums1990 wrote:Ok.

How can I ensure that my speaker system is NOT grounded ? Should I look for 3-pin to 2-pin plug converter ?tgdrums1990 wrote: 2.)

Thanks for your help
If it is ground hum (ground loop ), try something like this :
