Alex Narest bcf91808a2 Allows audio bitrate allocation in video calls without enabling TWCC (Transport Wide Congestion Control as defined at https://tools.ietf.org/id/draft-holmer-rmcat-transport-wide-cc-extensions-01.html) for audio stream.
This will allow experimenting with audio bitrate allocation in video calls without increasing transport overhead.
