How to use hls audio only with multiple audio tracks?

[axelverdruye]

Im trying to play an m3u8 master playlist that contains 2 audio channels. Each channel has its own playlist.
This works but when switching in the player itself (the language picker) it doesn't swap audio source.

Is there a bug or something wrong with the playlist? I don't seem to find any info concerning this.

Thanks in advance
