0.17.5 playback issue with TRUEHD audio

[BoxenOfDonuts]

Describe the bug

1. Go to a show or movie with truehd audio set as default
2. Attempt to play the file
3. Loads to black screen, never starts

If I set the bitrate low to force it to transcode, playback works with no issue.

If I remove the audio track with mkv tools, playback also works with no issues

I faced the same issue and it was because my device does not support TrueHD. It seems your Fire TV does not support it either (see its specs).

The problem is in ExoPlayer, which gets stuck in this state instead of throwing an error.

You can try different workarounds to play the media:

• pause the player while it's stuck, select another audio track (if you have it) and resume playback
• use an external player
• set the audio behaviour to "Downmix to stereo" in the app settings to force audio transcoding
