Hi paulosoaresf

I see that you're having issues with your Mac's speakers. I can appreciate wanting the speakers working well, and I'm happy to help. Please try resetting the Mac's SMC using these instructions:

Reset the System Management Controller (SMC) on your Mac

Thanks for using Apple Support Communities.

Cheers!
