Describe the bug
When selecting one of many possible audio tracks for playing a movie, Jellyfin fails with the following message:

There was an issue with the client profiling and the server isn't sending a compatible media format.

In the case where EN is the system default, this breaks the default play action for this movie until the audio track is changed back to one of the audio tracks that do work (and the change doesn't stick).

This is the mediainfo output for the file in question. Since the issue pertains to certain audio tracks I have not included the full output but only what difference there is between the audio (titles redacted):

  • Audio #1 (Default, Dolby Digital) works.
  • Audio #2 (AAC) works.
  • Audio #3,4,5 (Vorbis) does not work and crashes the playback.

Note that Audio #1 is not used as the default in my Jellyfin instance since I default to EN audio, making this playback broken without any user action.

The end of the most recent ffmpeg log on failure looks like this:

System (please complete the following information):

  • OS: Debian GNU/Linux 10 (buster)
  • Virtualization: N/A
  • Clients: Firefox Browser
  • Browser: Firefox 77.0.1
  • Jellyfin Version: 10.5.5-1
  • Playback: Transcode
  • Installed Plugins: Fanart
  • Reverse Proxy: None
  • Base URL: None
  • Networking: No NAT
  • Storage: Cloud

To Reproduce

  1. I'm unsure what exactly about this file breaks Jellyfin, but if you have one it should be as simple as choosing the erroneous audio track from the Web GUI
  2. Play it, and it fails
  3. Your "Play" button is broken for this movie if your preferred language is EN and it's non-obvious that it's due to the audio change.

Expected behavior

  • It would be helpful if the error message indicated that the problem was specifically audio conversion, and what to do about it (if anything)
  • It seems reasonable to expect that this file should be able to play. It plays fine in Plex and locally.
  • Perhaps the Jellyfin behavior should change in cases where the default audio track leads to a failed play: make the next attempt with the file-default audio track instead of jellyfin-default?

I'm unsure what exactly about this file breaks Jellyfin, but if you have one it should be as simple as choosing the erroneous audio track from the Web GUI 2. Play it, and it fails 3. Your "Play" button is broken for this movie if your preferred language is EN and it's non-obvious that it's due to the audio change. **Expected behavior** - It would be helpful if the error message indicated that the problem was specifically audio conversion, and what to do about it (if anything) - It seems reasonable to expect that this file should be able to play. It plays fine in Plex and locally. - Perhaps the Jellyfin behavior should change in cases where the default audio track leads to a failed play: make the next attempt with the file-default audio track instead of jellyfin-default? **Screenshots** ![image](https://user-images.githubusercontent.com/735192/84589322-01ca8680-ae2e-11ea-921b-2c753d367c73.png)
