Users can click on the language interpretation button to change the audio track. When they select a different language, they have the option to overlay the original audio so you can hear both audio tracks at the same time. There is also an option to mute the original audio and only listen to the second audio track.
The problem is that even if you mute the original audio on the front end / UI, the original audio still plays. Users hear both languages at the same time. This issue appears often from attendees point of view.
