The left speaker on my 15 inch 2017 Macbook Pro works for a couple of seconds and stops afterwards with a popping sound. Tried resetting NVRAM, SMB with no luck. Any thoughts?

Try making changes to preferences

>System Preferences>Sound balance etc.

Also from Applications/Utilities/Audio MIDI setup.app

Get help if the internal speakers on your Mac don't make sound

Same issue on External speakers ?

If no then I suspect you have hard ware issue.
