Again it's just easier to post here rather than create an entire thread for it.
I have a festering troll of a problem that just refuses to leave me alone, and it's
blasted bloody speaker noise. I used to have just bare-bones stereo speakers. I then upgraded to 2.1 near the beginning of the year, and for whatever reason that escapes me, the speakers emit a constant fuzzing sound. After trying different cables and different devices and finally just plugging everything into the wall sans inputs I concluded that as long as the speakers have power, they emit that fuzzing noise; and it's not like a quiet subtle sound either; if you stop and listen you can hear it across the room.
So being fed up with those I upgraded again to
5.1 today with
these guys (Logitech Z506).
And guess what. Same shit just not as bad, and sounds like a hard drive that's working in the background. I went through the same diagnostics as last time and conclude that as long as they're receiving power, they do this, and
all five of them do it (center channel is the worst, followed by the FL & FR, then the RL & RR). Actually if the center is connected its noise is even worse than the last set.
If it means anything I'll also point out that with the previous 2.1 set, the higher the volume on the physical dial the louder the noise. With this 5.1 set it's constant regardless of volume.
I suspected that it may be line noise as I just have the sub plugged into a 6-tap with four other things plugged into it (if that's at all how that works), so I relocated to a power bar and then an extension cord and... same thing.
Important note, for whatever reason, one particular time I reseated the VGA-esc cable that connects the main (has the vol-knob) front-right to the sub, the hard-disk-noise just quit. All was well for a few hours and now it's doing it again. >< Thus I don't have a stance on connection integrity.
So do I just have horribly shit luck with audio or is there anything at all I can do?
tl;dr version:Two sets of speakers that emit fuzzing noises as long as power is applied.
Really,
really shitty coincidence or something I'm missing?
