It depends on the model year of your MacBook Pro. The model and year can be found in the ➙ About This Mac menu option.
Regarding the speakers boot into Safe Mode according to How to use safe mode on your Mac and see if the problem persists. Reboot normally and test again.
Note: if you have a wireless keyboard with rechargeable batteries connect it with its charging cable before booting into Safe Mode. This makes it act as a wired keyboard as will assure a successful boot into Safe Mode.
Next Create and log into a new, basic, admin user account, Set up users, guests, and groups on Mac, and see if the problem persists. This tells us if the problem is limited to your user account or is system wide.
Note: do not launch any 3rd party apps in the account so as to not install any of the supporting files that most create.
If the problem isn't present then your original account has software installed that is causing the problem. If the problem is present you should make an appointment at the nearest Apple Genius Bar or Apple Authorized Service Provider for a free diagnostic check. NOTE: if the MBP is still under warranty the diagnostic check will be free at both. If it's not in warranty only Apple will provide a free check.
