I've recently had problems with calls from the Microsoft Teams desktop app. Anytime I join a call, I can't hear the audio of any other participants or speak. Input/output devices have been set and work fine for all other apps. The sound effects within Teams also play. To participate in any calls, I have to join via the web version. Is this an error on my side or a wider bug? And if it's on my side, how can it be fixed?
