Audio problems while playing streams

Good morning, guys.
I'm playing my IPTV list (public streams, nothing illegal) on my Zgemma H7S through xtream-editor.
One of these streams (this is the link) is being played flawlessly but no audio comes out of it.
I've changed the settings on my Xtream Editor using alternatively exteplayer or gstreamer but nothing changes so I think it's something depending on codecs.
Is there a way to install a complete player on Enigma2 (something similar to mpv, to be clear) or a "full" audio plugin?
Thank you very much.
