#178 aac audio failing to pass-through when using direct copy

[Matthew Bentley]

.mp4 captured by geforce experience (shadowplay), fltp aac 48khz audio, select direct stream copy for audio, when going to 'save as' the output format for audio comes up as PCM. Save out, confirmed output is PCM audio; should be aac.
