Hi there
No titles in my stream. I guess it's because of my DNAS.
Just want to know should I upgrade to 2.4? or roll back to 2.1?
In any of the cases, can somebody please tell me the command line to do it?
Thank you so much and sorry for being such a noobie

you should go to 2.4 to resolve the title issue rather than going back to 2.2.1 (i assume that's what you mean as there was never an officially provided 2.1 release).

though the title issue was resolvable via a DNAS config change but it's better to use 2.4 as it improves the title handling in relation to HTML5 audio / Flash players and clients which do support the in-stream metadata.

Fixed !
Thank you DrO.
