Your question

Is this type of hiss/white noise normal?

First of all, my setup:

OS: Windows 7 x64
Motherboard: GA-EP45-UD3R
Onboard Sound: Realtek HD ALC889A
Speakers: Logitech X-540
CPU: Intel Q6600
Video Card: Radeon 4870
HDD: WD 640GB
PSU: PC Power and Cooling 650W
Case: Antec 900


Scenarios:

Speakers on with no sound - Hiss on center speaker only (variable with volume knob after about 33%)
Speakers on with stereo music - Hiss on center speaker only (variable with volume knob after about 33%)
Speakers on with movie - No hiss (perhaps drowned out by real sounds)
Speakers on with video game - No hiss (perhaps drowned out by real sounds)


I just bought the X-540's and I'm no audiophile but the hiss has been driving me crazy for a few days now. Do I need to buy a sound card or try digital speakers? Are my new Logitech's faulty or is the hiss normal? Please, someone who knows alot more about sound, help a guy out.

Try setting the volume on your system not the speakers to about 70%, some amplifiers generate noise when running at full volume so setting your system volume lower and increasing the speaker volume should help you reduce this a bit.

Didn't solve the problem. That actually seemed to make it worse since the static seems to stay proportional to the volume knob on the speakers while the music is much lower due to the system volume being down.

Thanks for the reply though hunter.


*edit* Oh and I forgot to mention that I moved my cell phone away and shut off all electronic devices in my room to minimize interference.
