Attached file videos.zip

User Agent: Mozilla/5.0 (Windows NT 6.3; Win64; x64; rv:88.0) Gecko/20100101 Firefox/88.0

Steps to reproduce:

  1. Unpack the attached "videos.zip" file
  2. Open each file in Firefox 88.0.1 (64-Bit)

Actual results:

  1. File "16bit-pcm-audio.mp4" plays with sound muted. Unmuting doesn't work.
  2. Files "24bit-pcm-audio.mp4" and "32bit-fp-audio.mp4" both give "Kein Video mit unterstütztem Format und MIME-Typ gefunden" (No video found with supported format and MIME type) error message. Videos don't play at all.

Expected results:

All videos should play with sound (same as they do in Google Chrome 90.0.4430.212),

The Bugbug bot thinks this bug should belong to the 'Core::Audio/Video: Playback' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.
