Laptop builtin speaker not working

I am looking for a freelancer who can help me fix the issue with the built-in speakers on my laptop. I have already tried troubleshooting the issue myself, but unfortunately, it didn't work.

Requirements:
- Experience in troubleshooting laptop speaker issues
- Proficiency in working with Windows operating system

Additional Information:
- The laptop only has the built-in speakers, and there are no external devices connected to it.
