Macbook Retina cracking sound when muted
Hey guys,
I just found that my Macbook Pro with Retina display makes a litle cracking sound when trying to play an alert, even when muted.
Not sure if it's an issue or a normal behaviour.
You can check if yours makes this as well when turn off the sound and make your mac play an alert sound, e.g. go to System preferences and press cmd+j (this is an invalid shortkey that's why it will try to play an alert sound). The cracking sound is not really loud so listen carefully.
Please let me know how it went.
The local AppleStore is really far away from me so I don't want to lose a day for invalid issue, that's why I need your help.
Thank you!
