It can be frustrating while you are on call in MS Teams with your colleagues, clients or important people, and you need to increase or decrease the volume, but you can’t.
The issue is irritating, especially if you need to hear or be heard more clearly.
In this article, I will point out the reasons why you can’t adjust the volume in MS Teams and how to fix it.
So, without further ado, let’s begin.
Why Can’t You Adjust Volume in Microsoft Teams?
Due to outdated PC audio drivers or the MS Teams application, inaccurate Teams audio settings, mute microphone, incorrect headset or speaker input, you can’t adjust the volume in MS Teams. Also, the issue can occur if your microphone sound is off for MS Teams from Windows settings.
Below, I have briefly discussed the reasons. Check those out.
Take a look at the causes of why MS Teams is unable to adjust the volume:
Outdated MS Teams or Audio driver
There should be an audio driver software installed on your PC. If that driver is outdated, you may be unable to change your PC volume via Teams. On the other side, Whether you are using an old version of Teams, it may not be capable of changing your computer’s sound.
Inaccurate Windows & Teams Sound Settings
Due to some random bugs, your Windows and Teams sound settings may get changed. If the settings are not as it is supposed to be, you can’t upper or lower the sound from MS Teams.
Headsets or Speaker Plugged in Incorrectly or Mute Microphone
Most users like to make conversation using their headsets, speakers or AirPods. If the device you are using on your PC is not connected correctly, you can’t control the sound.
Moreover, if the microphone is mute, you will hear no sound. Also, you won’t even realise whether the sound is too loud or low.
These are the factors that can cause you trouble not allowing you to control the volume in MS Teams. In the following section, I have explained what you can do to avoid this issue.
