Live streaming language issues when using interpretation

We have just done a webinar with 5 languages (English, French, Spanish, Hindi and Arabic) and we streamed live to facebook live.

All went well, but we noticed the audio feed to facebook was the original “floor” language and not the language the host is listening to (i.e English) Therefore, the feed was useless unless you spoke 5 languages and only had limited participation. If the meeting is in one language, it is not a problem.

Solution: Change this live streaming audio to be able to be whatever the host hears, so if pick English, we hear the English interpreter?

Or is their another solution?
