Good morning.

So Yesterday I bought Cyberlink Power Media Player (for Surface RT through Windows Store), and so far it's been working so-so.

Firstly, there are some mkv that Power Media Player plays but there is no sound (especially if there are many soundtracks in a mkv).

Secondly, when a mkv has multiple subtitles tracks, Power Media Player does not allow me to choose any of those tracks, it only allows me to add any external subtitle (like .srt for example).

Is there a way to choose another soundtrack or another subtitle track?

I'm posting the info of one of the many affected mkv (this one has no sound and does not allow to choose a subtitle track):

Can you please check what's going on, and why I have no sound and subtitles?
