Hello, The laptop fans were annoying me, so I read somewhere I should reset the SMC. I did that by shutting down and holding Shift+fn+ctrl+power. However, after that the MBP audio stopped working. The only audio working was at the start (when you have the white screen with apple logo). I have no clue what to do to make it come back, obviously if it works at the beginning the speakers shouldn't be broken but I don't know where to look in the software Thank you in advance for your help!
