Greetings!

This is Tin, install MS Office on computer usually don't affect the sound. Most likely this is about the driver. No worries, I'll do my best to help. Please send the make and model of your device. (Please press Windows key + R and type msinfo32 and hit enter, look for system model)

Kindly send the version or build of your Windows (Please press Windows key+R and type winver and hit enter)

Will wait for your response.

Thanks,

Tin

Buying or installing Microsoft 365 does not remove or disable sound on Windows. The issue is almost certainly with Windows audio settings, devices, or drivers, not with Microsoft 365 itself. Try these steps in order:

1. Run the Windows audio troubleshooter (Windows 10/11)
   Use the Get Help audio troubleshooter, which automatically runs diagnostics and attempts to fix most audio problems.
   If it doesn’t fix the issue, continue with the steps below.
2. Check the output device and volume (Windows 11 example)
   1. Select the Speakers icon on the taskbar.
   2. Select the arrow to the right of the volume slider (Select a sound output).
   3. Make sure the correct speakers/headphones are selected.
   4. Make sure the volume is not muted or at 0.
3. Check sound settings and that devices are not disabled (Windows 10 example, similar in 11)
   1. Right-click the Speakers icon on the taskbar and select Open Volume mixer.
   2. Ensure none of the volume controls show a red muted icon; if they do, select them to unmute.
   3. Go to Start > Settings > System > Sound.
   4. Select the output device, then Device properties.
   5. Make sure the Disable checkbox is cleared for both output and input devices.
4. Set the correct default audio device (especially if using HDMI/USB)
   1. In the taskbar search box, type control panel and open it.
   2. Select Hardware and Sound > Sound.
   3. On the Playback tab, right-click the correct speakers/headphones and select Set as Default Device, then OK.
   4. If an external monitor without speakers is set as default, change it to real speakers/headphones.
5. Check that an audio device is installed and drivers are working If Windows shows “No audio device is installed” or similar:
   1. Open Device Manager.
   2. Check under Sound, video and game controllers that an audio device is present and not showing an error.
   3. If needed, install or update the audio driver from the PC or motherboard manufacturer’s website, or roll back to a previous version if the issue started after an update.
   4. Run the Playing Audio troubleshooter from Settings > System > Troubleshoot > Other troubleshooters.
6. If sound is missing only in Office apps (Excel, Word, Outlook, PowerPoint) If the system sound works elsewhere but not in Office (for example, no send/receive sounds in Outlook):
   1. In any Office app, go to File > Options.
   2. Open the Accessibility or Ease of Access tab.
   3. Under Feedback Options, check Provide feedback with sound to enable Office sound effects.
   4. Optionally choose Classic in Sound Theme if the original Office sounds are preferred.

Microsoft 365 does not need to be uninstalled or quit to restore sound. Once Windows audio settings and drivers are corrected, sound will work again in Microsoft 365 apps and the rest of the system.
