Additional team and channel-related features and issues within Microsoft Teams for Education
Hi MAW1960,
Glad your post your question sir, my pleasure to assist you.
If your audio device is function properly as you mentioned on voice recorder, back to teams clients, we would like you to make a test call to see the results:
At the Teams client, click your Avatar, Devices and make sure your audio devices has already showed up, then make a test call and to test it out if you could hear anything:
In addition, we would like to confirm if you are using PCs. Make sure both parties (yourselves and other side)select the cog wheel on top right and have selected the right input devices.
Kind Regards,
George
