OpenTalk: no microphone input from bluetooth headsets?

RRRR shared this problem ago

Sometimes when I invite people for an OpenTalk call, none of their audio is transmitted even though they are unmuted. (OpenTalk recognises this, displaying the red warning symbol in the upper left-hand corner.) Most recently someone managed to fix this by switching from their bluetooth headset to the built-in microphone. This user had a Macbook, but I don't know which browser.
