Screen Recording of Teams Meeting - No Audio

I used Stream to record my screen for a Teams meeting. The objective was to capture the video image of all 9 meeting attendees wishing farewell to a retiring colleague (since Teams recordings only capture video of 4 people).  The screen video captured all attendees but no audio other than my own voice. I tried recording several times...with and without headset. Each time, I could hear everyone but only my voice was captured on the video. How do I correct this?
