Switching Teams computer audio fails after using Zoom.

Hi @Vijay Mahto,

Welcome to the Microsoft Q&A forum.

I would like to provide you with the following information:

Based on your description, the audio works correctly after you restart your PC. To troubleshoot this issue, after ending a Zoom or Teams meeting, please make sure to fully close the application, including any background processes, and then check whether the issue still occurs.

In addition, before starting a Teams meeting, please open Teams, click on your profile picture, then select Settings > Devices, and check whether an available audio device is listed.

If you see the correct audio device in the Teams settings, you can try clicking “Make a test call” to test the audio and video. You can review the test results there.

At the moment, I do not have a test environment for Zoom. However, you can refer to the following documentation to learn how to configure Zoom settings before starting a meeting, in order to avoid the issue mentioned above:

Configure and test audio independently in both Teams and Windows so that switching apps does not break sound.

1. Verify Teams is using the correct speaker
   • In Teams, select Settings and more "> Settings > Devices.
   • Under Audio > Audio settings, choose the desired device in the Speaker dropdown.
   • Select Make a test call and confirm the test playback is audible.
   • If the device does not appear, charge/reconnect it (Bluetooth) or unplug/re‑plug it (wired), then reselect it.
2. Check speaker during a Teams meeting
   • In a meeting, select the arrow next to Mic.
   • Choose More actions > Audio settings.
   • Under Speaker, ensure the correct device is selected and not muted.
3. Confirm Windows is not switching the output device
   • From Start, open Sound settings.
   • Go to System > Sound.
   • Under Choose where to play sound, select the same speaker/headset used in Teams.
   • Make sure Volume is not set to 0 and is not muted.
   • If the device is missing, select Add device and pair it again.
4. Re‑enable audio device if it disappears
   • In Sound settings, go to Advanced > More sound settings.
   • On the Recording tab, right‑click the mic and select Enable if it is disabled.
5. If audio still breaks after switching between Zoom and Teams
   • Update to the latest version of Teams and install the most recent Windows updates.
   • If the speaker stops working system‑wide (not only in Teams), reinstall or update the audio driver from Device Manager, then re‑run the steps above.

These steps ensure Teams always explicitly uses the correct speaker and that Windows does not leave the device muted or disabled after switching from another conferencing app like Zoom.
