Managing sound and video settings during Teams meetings and calls for optimal communication
How did you manage to send you a new dongle?
When contacted them about the same issue and requested a dongle, they refused to send me one and wrote this to me:
"Actually, this is the setting of the headphone. It is a mute reminder of your headphone. Since it is a factory setting, there is no way to change/turn off it by the end user.
We will forward your request to engineering. Hope this could be canceled in the future"
