Description of problem or question:
When I convert one particular file the audio is garbled. It looks like normal PCM audio to me but the output sounds more like AC-3



Steps to reproduce the problem (If Applicable):
Convert the movie Paper Moon using Apple TV 1080/60 profile



HandBrake version (e.g., 1.0.0):
1.7.2



Operating system and version (e.g., Ubuntu 16.04 LTS, macOS 10.13 High Sierra, Windows 10 Creators Update):
Windows 11
