Hi there, lets see if we can solve this!
I guess you are new to reporting issues, so lets clear some things up
Usually, I access MS Teams meetings via the links that are shared with me
That is irrelevant and doesnt tell us HOW you use teams.
Teams is a web app, which browser? There is also an electron wrapper which basically gives you a chromium browser with a webapp with elevated privileges and more local storage. I would highly recommend to only use Teams in Firefox or Brave as it is malware and will absolutely try to spy on you.
And then the next question, how did you install the app? KDE discover shows you the source, so please tell us.
If it is a flatpak (which I assume), try this
flatpak list --installed --app
In case you run the electron app as a flatpak (if there are no big reasons for this please just use it in the browser), this might be a pulseaudio issue.
The microphone might be accessed via pipewire (which is good for privacy as otherwise any app could spy on you without you knowing) or directly via hardware somehow.
In systemsettings, to to application permissions and flatpak permissions (they hid that away which is annoying). You can just search for “flatpak” in the menu and it leads you to the settings page.
There you could see if the app (which I dont recommend) has no pipewire access.
It might be a different issue totally. You also only mentioned teams without mentioning anything similar. If you install Brave or other apps, does sound output work?
Have you tried selecting something else than “duplex” for output?
































Odd, as you are on fedora, a wild guess is teams might use DRM or a nonfree audio codec like eac3 (and afaik aac too, which is sadly the standard for many things).
Try installing libavcodec-freeworld from rpmfusion or better use their approach to replace ffmpeg with the full variant and install the freeworld codecs.
