Humming in 5.1 speakers

[Redien]

Hello,

please i have a problem with my speakers, I have Genius SW-5.1 4000 and they started to humming. I have integrated and external sound card (Sound Blaster Audigy FX, which i use), I try to switch but they are humming in both connections. When I mute them, they stop with the hum immediately. At the beginning it didn't bother me that much, but as time passed it started to be really annoying so I mostly use headset at the moment.

Please if anybody experienced it before and fixed it or any advice is really helpful.

Thank you in advance
Best regard

Might be a grounding issue. It's a very common issue.
Just Google it for any guides on how to fix it.

Have you installed any new electronics near the speakers or fluorescent lighting?
