Speakers: 'An Ambient-Hissing Noise' (EdifierS1000DB)

[GuNjAX_3030]

I just got a Pair of the Edifier S1000DB bookshelf speaker, which I'm very pleased with but when when the speakers aren't playing anything, just 'On and Idle' I can hear a low hissing noise from both speakers. To hear it I have to place my head right next to it so it dose'nt bother me at all when I'm actually playing Music, Youtube, or playing games. Is this something I should be concerned about? Is something wrong here? Can this be fixed? I have it plugged into my Sound BlasterX AE-5 (Pcie) Soundcard, VIA 3.5mm AUX Input. Thank you for your time reading this and giving me any helpful suggestions.

There could be a few causes for this, a high noise floor either in the output from the sound-card or input to the speaker, mild EMI because you're running an unbalanced analogue connection, EMI within the sound-card, connectors starting to fail.

 

The easiest solution to this is to use the optical output from your sound-card and the optical input to the speaker. You just need to buy a toslink cable long enough for where you place the speakers.
