Ok so I softmodded my wii about a month or so ago.

My sister then asked me to do hers and I followed a different tutorial to the one that i used as it wasn't online anymore

Well to cut a long story short the wii now has no sound apart from the one from the controller

Does anyone have an idea as to what has caused this and do you think I will be able to sort it without re installing the wii from the NAND backup??
