You are welcome.
I do not think that would play any part, if compressed air did not fix this.
So, try the following, in the order provided.
Scan for Malware:
Start with running a scan for malware, using Malwarebytes for Mac and remove what is found.
Next...
Reset your SMC and your NVRAM:
Sometimes changes are made to the system and then settings (i.e. for the speakers) become manipulated, technically. So, reset both on your Mac.
Next...
Create a New User, and See if that Works.
If so, then it is something installed/configured on your current user that should not be. So, transfer everything over to the new user, and then trash user. You should be good from there
Next...
Boot into Safe Mode:
Hold Down the Shift Key upon boot. Once at the login screen, release shift. See if it all now works. In Safe Mode, only necessary items load (i.e. the caches), and new preferences are set aside.
If nothing above works, then...
Reinstall the macOS:
Nothing would be lost, it's just that sometimes changes are made to your system, and then then processes become corrupted, technically. When reinstalling, deleted files are reinstalled, and misplaced files are moved back to where they should be. Go Here: How to reinstall macOS from macOS Recovery - Apple Support.
Back up your Mac Prior to the Reinstall:
Are you Concerned of Losing Data?:
- If not, just move ahead and erase the disk and then install the macOS.
- If so, then first backup your macOS.
Start by Creating a Time Machine Backupof my Mac. That way I could be assured that Incan recover my Mac, should I need the App back or if anything goes wrong due to the removal. So, Create a Time Machine backup of your Mac, so that you can have something to restore your Mac from, should anything go wrong with the reinstall.
