Remux Dolby Vision Audio becoming PCM

[TheDreadPirate]

Edit: Ah, looking at Jellyfin logs, it seems it might be remuxed to HLS-TS, which could be part of the issue. My client currently has "Prefer fMP4-HLS Media Container" unchecked (default). Perhaps setting this would force an mp4 remux...will have to try that and compare results.

IIRC, prefer fMP4 is currently bugged in WebOS.  I can't recall if this is a WebOS problem or a Jellyfin problem.  It USED to be on by default but has since been off by default on WebOS and should stay off for now.
