How would i fix subtitles.

[Matterom 0]

So i am running on Version 3.0.5675.1 and one of the issues i have come across is internal subtitles on files not actively registering, on any of my files.

 

Other than one or two exceptions subtitles and alternative audio languages are not appearing as options, regardless of client. As i am using linux and have very little idea how to use folder perms or ACL i naturally assume it is User Error, But i figured i would check here just in case it was not entirely a Linux issue.
