    I am trying various apps to transcode an mkv to mp4. It generally works fine, but when it comes to audio, a 5.1, 6 or 7.1 channel audio file will generally come out as a 2 channel audio stream. I am converting from either DTS-ES or AC3. The 2 channel audio does report Front: LFE and Back: LRC (or some such) same as the 6 channel I converted it from. Does AAC not require 6 channels to output all those channels?
