I have had this 4.1 speakers for the last 4 years and they have been outstanding on sound quality.
Long post, I am trying to cover all details.
For some reason, when I switch to the digital choices (Prologic / Quad) I get an incessant pops and crackling noise that over takes the sound.
The other Analog modes (Stereo, stereox2) work just fine no crackling.
Dolby digital works fine and sometimes crackles, but nothing like Quad Mode and Prologic. (Quad mode enables surround sound as Front left, front right, rear left, rear right) and then the subwofer.
I though it was the computer's built in sound, since the problem seemed to start when I upgraded to a new system that came with built in sound in the motherboard. (Realtek) so I bought a new sound card (E-bay / Audigy) and disabled the realtek on board sound. The crackling noise persisted.
I unplugged the speakers completely off the computer, just the power and the crackling sound persist in the (Quad and Prologic Modes)-- So I assume it is not the computer or sound card and it is something on the electronics enclosed in the subwofer housing.
Is it Power noise? wireless network noise? Ethernet cables noise? there is quit a bit of wiring around it but the wiring amount has not changed.
The only things that have changed are: Wireless router, new motherboard.
I have unplugged the wireless router and had no effect, the crackling still there. I power down the entire office, just letting the sound system plugged in and the crackling noise still there. I bought New Belkin surge protectors, and from there they are plugged to an APC UPS and from there into a power strip. the crackling noise still there.
I am thinking something in the electronics board had been affected.
This thing of crackling noise is similar to the noise when wires are making poor contact. Needles to say I have checked all the wiring is in good conditions and all the fittings and couplings are tight.
I am looking for options before I ave to crack the subwofer open and look for bad caps or coils.
Thank you for any suggestions.
Is it bad caps or coils what I have to look for? Or is there more to this crackling noise.
