On Jitsi, some interlocutors have their microphone that does not work. No one can hear them, but they can hear us.
This phenomenon occurs both on meet.jit.si and on my own dedicated installation.
I took control of their computer via teamviewer… the sound setting is perfect ; I have had the message “jitsi meet need to use your microphone and camera” And, of course, I click YES ; I tried with Firefox, with Chrome : same issue !
Moreover, these interlocutors tell me that everything is working well with zoom and teams.
I do not understand.
Thanks a lot for your help.
