Hello Everyone, Today if I'm posting ,it's because I'm in front of a "small" problem. First : it's a nTB MacBook Pro 2016 and I'm on Sierra with 10.12.2. I noticed that sometimes the speakers where playing a little sound/noise like "tick",like the sound when you plug a mic in some computers and it comes from the right or the left speaker. Most of the times I have this little sound popping when I'm playing a video or a little after videos ended . I ear this sound too during the startup of the Mac (not at each start). I want to know if it's a hardware issue or software ? I think it's a software problem because it 's not linked to a volume too high or bad audio of what I'm playing. If you are experiencing this or if you have a solution , a news , let me know it please. Have a nice Day and sorry for my English I'm French .
