Solved! Subwoofer oopmh sound every 2 sec

[madsnil]

I got a multimedia sound system yesterday, its a Tracer Hi-Cube trg-495 2.1 sounds system..

Now I've noticed that it makes a Ooomph sound every like 1-2 seconds, sometimes with scratching in it ..

The system is connected via a 2RCA mini jack.

I've trouble shooted a little bit and I found that its not a problem with my pc, nor cables.
I tried putting the speakers into another power suply, but it didnt work.

turning the speakers in at the store is not really an option for me, as I bourgt the speakers when i was on holiday in Poland.

Sounds like it's a bad sub. Did you try another source? Maybe a phone output or mp3 player or something aside from the PC?
