When using the wiimote for anything, the speaker would stop playing sounds for no reason. I check the volume but turning it up or down doesn't help. The sounds would only show half way then cut off. The batteries are fully charged in the Wiimote and they have not been changed recently, nor are any mobile/cell phones nearby. Would some faulty wiring inside the Wiimote be the case and would I be able to get a replacement or have it repaired?
