Well...have tried it every which way I know how, and it just doesnt seem to work for me. No matter which audio codec I use, whenever I upload my demo reel, it uploads without audio. I've done it based on the specs on the site, and it still comes out audio-less.
My video settings when uploading:
H.264 video 640x360
MPEG-4 Low Delay AAC Stereo 48khz audio
Have also used 16-bit integer (Little Endian)Stereo 48khz audio.
