Try restarting the services using Command Prompt:
- Press
Windows + X
and select Windows Terminal (Admin) or Command Prompt (Admin). - Run the following commands one at a time:
net stop audiosrv net stop AudioEndpointBuilder net start AudioEndpointBuilder net start audiosrv
- Check Windows Update

- Run System File Checker
Corrupted system files can cause issues with services:

- Run:
sfc /scannow

Sometimes reinstalling the audio drivers can fix issues:
- Right-click the Start button and select Device Manager.
- Expand Sound, video and game controllers.

- Restart your laptop; Windows should automatically reinstall the drivers.
- Check for Malware
Malware can interfere with services. Run a full scan using Windows Defender or any other reputable antivirus software.
- Restore Your System
If the issue persists, consider performing a system restore to a point when everything was working:
- Search for Create a restore point in the Start menu.
- Click System Restore and follow the prompts.
If none of these solutions work, you might consider seeking assistance from a professional or a tech support forum for more personalized help.
