Hi Mallikarjun,
Have you tried running the Surface Diagnostic Toolkit? It’s a free tool from Microsoft that can automatically detect and fix common hardware and software issues, including audio problems.
You can download it here: Microsoft Surface Diagnostic Tool
Once installed, just run the tool and follow the prompts. It will check your device for missing drivers, hardware issues, and other potential causes of the audio malfunction.
Let me know if that helps or if you need further assistance!
Best,
Jeric
