I have an MP4 video file, that on the ATV the video plays but there is no audio. This is the case whether I play it via Home Sharing or through Plexconnect. If I force transcoding via the Plexconnect settings, the audio does play. My question: Does anyone know why this is the case and is there anyway to get the audio to play without forcing transcoding?

Here is what I know about the audio stream in the file:

The maker says Audio 1: English | 128 Kbps | 2ch | AAC

According to VLC media information:

Codec: MPEG AAC Audio (mp4a)
Channels: Stereo
Sample Rate: 48000 Hz

This is the video info:

Codec: H264—MPEG—4 AVC (part10) (avc1)
Resolution: 1920 X 794
Frame rate: 23.976
