What did you do?
Produce a DASH manifest containing multiple audio or subtitle tracks in different adaptation sets with the same language code but different roles.
What did you expect to happen?
Audio and subtitle tracks with the same language but different roles appear showing both the language and the role, and the user can select any of these roles.
What actually happened?
Audio roles are not visible. Only a single element for each language is visible. The user cannot switch between roles, and they probably don't even know more than one role exists.
Subtitle roles are visible as duplicates, but selecting one causes all of them to be checked in the UI, and only one is actually displayed. The user cannot select the role they want.
I can select these roles using selectTextLanguage and selectAudioLanguage, but the UI remains inconsistent.
