PVR IPTV Simple Client - default audio and subtitles

[mocarela]

So... it seems global KODI settings (Settings->Video->Playback/Subtitles->Preferred audio/subtitle language) do have effect also in PVR IPTV Simple Client after all.
The problem remains now only with channels that do not have audio/subtitle stream as configured one in global KODI settings (e.g. stream for the same language is named differently or does not exist at all). In this case the first one is picked when the channel is played.
However, what concerns related specific PVR IPTV Simple Client settings, they do not exist.
