So, ever since I got my iMac, it always makes noises when I plug in my headphones or unplug them. And now more recently when I wake the iMac up from sleep. It always makes the "Funk" sound from the sound effects menu in the settings, and sometimes the sound when you send an email. And it does this over and over again! It is the most annoying thing ever, and I'm not sure if its suppose to do that or if theres something wrong. Any help would be appreciated. Thanks.
