iMac makes weird noises when plugging in headphones

Everytime I go to plug in or unplug my headphones from the headphone jack on my 2011 iMac, it makes weird ding noises and the mail swoosh sound for a good minute. Why does it do this and how can I fix it? It has done it since the day I got it!

mac, Mac OS X (10.5.7)

i have the same or similar problem, iam really not sure about this - sounds stupid but it feels more like it plays the same "melody" when i plugin the headphones after some time (hours/days). like 4 times "new mail" 2 times "sent mail" + 1 "new mail". Very strange. I can not reproduce the sounds by unpluggin and pluggin the headphones again even if i get or send mails in between.

Right now, I wrote on the board on this behalf. I have the same effect of freezing the sounds until the headphones are plugged in again. This bug is in OS X since Lion (at least). I found it occurs if I use headphones for f.i. watching movies during night time and put the iMac into sleep afterwards. After waking it up again, those sounds are not played back and freeze until the headphones are plugged in again. Then, all works fine again. I dont see a solution for this.

On my MacBook Pro 13.3 Retina I hear a kind of white noise in the following cases:


1) Just after plugging-in my headphones and it lasts about 1 min.

2) Once a system sound (notification of smth else) has palyed. It lasts some 10-15 sec. and ends with a click sound.


I know that people are able to hear deferent frequences depending on their age: younger people can hear frequences that are inaudible to older ones. Thay would be nice that Apple finally fix it, as it's frustrating to work with headphones on.
