Managing sound and video settings during Teams meetings and calls for optimal communication
I've found this only happens with the default ringtone. Any others selected in Settings > Calls does not reproduce the issue. Any other thoughts? It seems like Win10 is pre-loading the ringtone as a separate system sound and plays manually/automatically.
When placing a call the default ringtone sound plays also regardless of your default ringer settings. It seems that anytime Win10 interacts with this specific sound it caches it to play on your audio device.
