Trouble playing video with dvdsub

[Subculture]

To resurrect an old thread, I'm having the same issue.

Jellyfin (10.10.6) on NVIDIA Shield, playing a file with AAC 7.1 audio and a DVDSUB (Vobsub) track fails with "Too many errors. Giving up"

Changing to "Downmix to stereo" allows the file to play fine with subtitles.
