Hello,
It's unfortunate to hear about your sound issue. This could be a result of various factors including incorrect sound settings, outdated sound drivers, or hardware issues.
Let's try to solve this step by step:
1. **Check your Speaker/Headphones Connection**: Firstly, ensure your audio device (speaker or headphones) are properly connected to your PC. Try connecting them to another device to see if they're functioning.
2. **Check Volume Mixer**: Right-click on the volume icon on the taskbar and open the `Volume mixer`. Check if the volume is muted or set to low for any apps.
3. **Choose the Right Playback Device**: Right-click on the sound icon in your taskbar, select `Sounds`, then switch to the `Playback` tab. Make sure the right device (your speaker or headphones) is set as the default device.
4. **Update Sound Drivers**: You may be experiencing problems due to outdated or corrupted sound drivers. Go to `Device Manager` (you can search for it in the Start menu), locate `Sound, video and game controllers`, expand it and right click your audio device, then choose `Update driver`.
5. **To check Windows 11's Sound Settings**: Click on the `Start` icon, then select `Settings` > `System` > `Sound`. Under `Output`, make sure the correct output device is selected. Under `Volume`, check that the volume is not set to zero and the sound is not muted.
6. **Restart Audio Services**: Press `Win + R`, type `services.msc` and press `Enter`. Locate `Windows Audio` and `Windows Audio Endpoint Builder`, make sure their status is `Running` and their startup type is `Automatic`.
If the issue still persists, it could possibly be a hardware issue. Try testing with a different speaker or headphones. If the problem remains, I would recommend having a professional check your PC for any possible hardware issues.
Let me know how it goes and if there is any other way I can assist. Good luck.
