Hello suraj9192,
Thank you for using Apple Support Communities!
I understand from your post that you have no sound preferences in the System Preference of your MacBook Air. I recommend testing the issue while your Mac is in safe mode and/or in a new user account. The following articles have the steps you will need to test the issue in both safe mode and in a new user account:

Use safe mode to isolate issues with your Mac - Apple Support

Best Regards.
