PVR IPTV Simple Client - default audio and subtitles

[mocarela]

Software
XBian version: 1.0 (knockout)
XBMC/Kodi version: 16.1 Git:2016-05-28-6f8e95d
Overclock settings: none

Hardware
Device type and model: Raspberry Pi 2 Model B
SD card size and make/type: 8GB Class 10
Network: Ethernet
Connected devices: TV

Problem description:
Is there a way to instruct PVR IPTV Simple Client to play specific (embedded) audio track and subtitles by default? Either through mp3 playlist or any other way.
If I select them for a particular channel it changes them for others afterwards.
It seems also that such general video settings in Kodi do not have effect in PVR IPTV Simple Client's Live TV.

Regards,

Alen
