Solved! Why my right speaker in BlasterX Katana dont work?

[Guri321]

To be honest i didnt even realise until yesterday that my right "bottom" speaker dont play any music, left upper and bottom speakers work correctly but i dont have clue what is wrong with the right bottom. Could anyone give me some advice?

Edit: connected via usb/micro usb (computer)

if only the one right bottom speaker is not working, the BlasterX Katana is defective:
