I have a windows 10 desktop, a windows laptop and an android phone. When I connect to a Jitsi meet using chrome on the windows devices other people can hear me. I cannot hear them. I am able to get two way sound on the android device. I have no problems with sound on the windows devices using chrome on any other task than Jitsi. I have checked the Jitsi settings for both of these devices. Appropriate microphones and speakers are recognized. I have checked the permission settings in chrome and Jitsi is being given full access.
The android access is satisfactory for small meetings but it is not for large meetings.
