I don't know how long this has been going on but I noticed it a few weeks ago. Whenever I turn on my speakers (Logitech X-530 5.1 system) there is a really low level buzz. I'm not playing any games they just have to be turned on.Any ideas?

Did you check all plugs and connections?Mic channel open ?

Everything is plugged in tight. I'm not sure what you mean by mic channel open, but my headset mic is also plugged in, but it still happens when I unplug it.

Re: Mic openI had a background noise once and it traced to the fact that the mic was "Hot" and adding noise to the system... moved mic slider to lower input setting. Understood, yours does it even if upplugged though.Have you tried bringing up the sound mix board software and turning off sound input/outputs one at a time?Do you have a sound "Wizard" program with your system? Might find problem for you.Has the routing of the wires changed? Unshielded cables closer to RF generating item?

It might be a bad amplifier, too. Or,..radio freq (RF) interference from poorly shielded power supply, power wires, etc.RhettE8500, Arctic Cooling Freezer 7 Pro, ASUS P5E3 Premium, BFG 8800GTX 756 (nVidia 169 WHQL), 4gb DDR3 1600 Patriot Cas7 7-7-7-20 (2T), PC Power 750, WD 150gb 10000rpm Raptor, Seagate 500gb, Silverstone TJ09 case, Vista Ultimate 64

If the speakers are powered by plugging into a wall outlet, try plugging into a terminal strip that has a built in filter - most good ones do. Might just be ac line noise or a DC transformer going bad.VicQ6600 G0 CPU 2.4 o/c 3.65Evga 680i A1 with P31 BIOS 2G XP2-8500 DDR2 1066FSB Mushkin 996535 RAM 5-5-4-12-2T320G 7200 HD partitioned for XP/Vista/Programs 2 - 74G Raptors in RAID0 500G 7200 HD for backup SATA DVD burner Evga 8800GTS 640 PCIx XG 175.16 702/1620/792Kandalf LCS case w/ built in liquid cooling 850W Thermaltake power supplyVisit the Virtual Pilot's Centerwww.flightadventures.comhttp://www.hifisim.com/banners/hifi-supporter-sigbanner.jpg

Poor ground, or more than one ground (ground loop) can get you as well..

Well the speakers are these ones:http://www.newegg.com/Product/Product.aspx...21126&Tpk=x-530They all plug into the subwoofer via RCA style cables. The wires are just little ones, not huge high-end speaker cable. The wires don't run too close to my PSU either. They all thread back behind my desk (where there is a cord jungle). also, it doesn't matter if I crank the volume knob, the humm is the same.

If the woofer has a built-in power supply, it is possible the woofer power supply has transformer hum.Also this noise could be cause by another piece of equipment in the room - by magnetic flux or through the wall socket wiring; even a fluorescent light can do this.

As an FYI, I use the same sound system without the problem.Many other things in a room can produce RF besides the computer's power supply..Move some wires around and see if it goes away or changes any.I've also had the problem on another sound system and replacing one of the leads cured it. Found the bad one by systematic subsitution using known good cable.Was one of the leads from sound card to amp.There is still the sound card to consider also.

About RF interference. I have our wireless router sitting ontop of the subwoofer. The wireless radio is enabled. Maybe that might be it?Well it's not that, I disabled it, no change.I also unplugged the green, black, and orange cords from my sound card ports, no change. It is only coming from the right front speaker. (Which happens to be the one that has the volume control on it, and the one that connects to the sub via the dsub cable.Alright, I wiggle the cords, unplugged all of them, blew the dust around (in my nose lol), and I can't hear it now, but I will wait a little bit, and see if it comes back
