> hello, i have same problem with you but i solved it. Just reimport your sound in C2 using WAV format. Then C2 will encode into multiple format, just press convert and OK button. Now don't remove any sound files. Export it again and now it should be working.

But that is the normal way to do ... what were you doing before ?.
I said source sound must be WAV format so that C2 can encode with the best result, so i talked about source file. I had test it using various format and the result not always working except WAV. You got it sir?
For 
luckyrawatlucky, send me your sound that have a problem i will convert it and i send you back. If i've much time i'll test by myself.
