How to change DVB player native language

Dear Friends,

our application is supporting native DVB playback, for this we are using the api from: https://www.tizen.org/tv/web_device_api/tvchannel

we’d like to enable the feature for our users to be able to change the audio language of the stream directly from our application, is there a way to control the Tv’s audio directly from an application?

I also checked the https://www.tizen.org/tv/web_device_api/tvaudiocontrol but this allows developers to only control the volume.

Thank You for any hint in advance,
Cheers!
