Hi Jess, Could you describe more detail on "I can hear the audio, but it doesn't sound correct", did it play correct audio but then continued with previous audio? or audio was played slower/faster? IMHO, it is rather unusual idea to replace the memplayer's audio buffer in EOF callback since you should make sure that the clock rate, channel number, and PCM length must be exactly same.
