I'm using blender 2.79b to edit a video. I'm not using it for 3d modeling at all. I edited the video in the VSE and everything plays fine from inside of blender. I then render the video to a file. I've tried every combination of audio codecs with the MPEG-4 container and H.264 video codec but every time the audio is either not present or is garbled when playing in Windows Media Player. Every case except for using Vorbis as the audio codec is garbled or not present when using VLC. I tried uploading the version using Vorbis to You Tube and the You Tube playback was garbled.
My searching and experimentation has reached its limits so I'm hoping someone can help me. Thank you!
