Posting this again:
We started experiencing this issue in the last 2 days.
- If an audience is joining using the web sdk, the last audience microphone does not capture audio.
- If anyone else joins or leaves the meeting the audio starts working
- We are also observing echo using SDK 1.7.8 which is not present in 1.7.7
Tested with web sdk, and versions 1.7.7/1.7.8
