Hi Renia,
Thank you for reaching out. My name is Furkaan, a user just like you. I’d be happy to help you with your concerns. Teams may encounter issues with certain audio codecs. While Teams itself doesn't explicitly list unsupported codecs, there have been reports of issues with certain sound drivers, particularly Realtek drivers.
We can explore the following:
Driver issues: As mentioned above, outdated or incompatible audio drivers (especially Realtek drivers) can cause issues with audio sharing in Teams. Try updating the audio driver to the latest version.
Codec Compatibility: While not confirmed, the team may not be able to handle certain less common codecs efficiently. If you have information about the specific format of the video that isn't working, an online search can reveal known codec issues with Teams.
System updates: Make sure you're running the latest version of Microsoft Teams and operating system. Updates often include bug fixes and compatibility improvements.
Test with a different video: Try sharing the audio from another video in a different format. This can help determine if the issue is specific to certain video sources, or if it's a broader codec compatibility issue.
If you have any additional questions or concerns, please don’t hesitate to reach out. Give back to the Community. Help the next person who has this issue by indicating if this reply solved your problem. Click Yes or No below. Best Regards, Furkaan
