Change audio track in a DASH

[pedrosilvabos]

Hello, @l1bbcsg , @reeFridge , @nomean42
VERSION: 2.7.5
DEVELOPING IN WINDOWS ENVIRONMENT
I would like to know how is it possible to change the audio track in a DASH stream.
In attachment i send a sample of an MPD file with multiple audio.

<AdaptationSet id="3" group="2" bitstreamSwitching="true" segmentAlignment="true" contentType="audio" mimeType="audio/mp4" lang="por">

<AdaptationSet id="4" group="2" bitstreamSwitching="true" segmentAlignment="true" contentType="audio" mimeType="audio/mp4" lang="eng">

is there a way to choose between these?
Currently the mpd loads with english audio, and I would like to let the user chose the prefered audio language.
I have tried to set my LG WEBOS TV language in Portuguese, but the result is always English
