Available audio channel can be changed via the player controls during runtime for live broadcasting or in recorded or replay programs.
Changing the audio channel is available for programs if provided by the TV station. 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.
To switch from one audio channel to another, simply click on the bubble symbol in the player. Please note that the language cannot be changed if dual-channel audio is not available for a certain program.
