no audio devices found connected to pc on lenovo laptop windows 11 just happened recently

It seems you are experiencing an issue with audio devices not being recognized on your Lenovo laptop running Windows 11. Here are some steps you can take to troubleshoot this problem:

1. Check Connections: Ensure that any external audio devices are properly connected. If you're using USB audio devices, try unplugging and reattaching them.
2. Restart Your Laptop: Sometimes, a simple restart can resolve hardware recognition issues.
3. Update Drivers: Make sure that your audio drivers are up to date. You can check for updates through Windows Update or the device manufacturer's website. For Intel Smart Sound Technology drivers, ensure you have the latest version installed.
4. Device Manager: In Device Manager, check under "Sound, video and game controllers" for any devices that may have a warning icon. If you see any, right-click and select "Update driver" or "Uninstall device" and then restart your laptop to reinstall the drivers automatically.
5. Run Audio Troubleshooter: You mentioned running the troubleshooter, but you can try running it again to see if it detects any issues that were missed previously. Go to Settings > System > Sound > Troubleshoot.
6. Check BIOS Settings: Sometimes, audio devices can be disabled in the BIOS. Restart your laptop and enter the BIOS setup to ensure that audio devices are enabled.

If these steps do not resolve the issue, it may be necessary to contact Lenovo support or check their forums for any specific solutions related to your laptop model.
