build 5158, 5160 fails to copy or transcode audio LC-AAC 6ch

[ysbinns]

I have many MKV files using LC-AAC 6 ch audio. To create an MP4 file, on Video tab I Copy Video and Auto Select for Encoder and Source, on Audio tab I Copy Audio and Auto Select for Encoder and Source. I tested files using audio LCAAC 2ch, LCAAC 6ch, AC3 2ch, AC3 6ch, MP3 2ch, and Vorbis 2ch. All MP4 files were successfully created EXCEPT for LC-AAC 6ch. This format gave me a 0.0mb output file.
