Description

I have a TV show with 5.1 ac3 audio where the first 4 minutes are a recap of last week, followed by the show. During the recap, only the Front Right and Front Left channels have sound, and the other channels are silent. Once the show starts, all channels have sound.

When I play the original 5.1 file through my headphones, everything sounds find. I extracted the audio, converted it to stereo using "-channels 6 -af hrtf" and remerged with the video. After this, the audio has buzzing during the recap, but it sounds nice and surround-y once the show starts (with volume on all channels).
