If you want to activate an available subtitle or alternative audio track during runtime for live broadcasting or in recorded or replay programs, please proceed as follows:
Playback of stream > Swipe down on Touch surface > Subtitle > Select language
Playback of stream > Swipe down on Touch surface > Audio > Select language
Changing the audio track or activating the subtitle is available for programs if provided by the TV station for a specific show. This is not the case on all channels nor for all programs. Only if the option is available, you will be able to switch to another audio channel or activate the subtitle.
