Loud Popping Noise when wake from sleep

Mine does this too. Do you think we should call apple?

I have external speakers that include a subwoofer (and small amp) that do not display this noise except when I unplug or plug in the mini jack (which is expected). Perhaps there is a connection problem - does the pop happen when it goes to sleep as well? On another note, do you have any applications that have audio outputs running when you put the machine to sleep? Just thinking out loud here.....

Mine does it too with external speakers - but if you keep the volume on the Mac higher and adjusty the volume to required level on the speakers - it reduces the pop in volume a lot. Whereas if you keep your speakers amplifier up loud and the Mac volume lower it's a lot worse.

yes I have external speakers, - Altec Lansing

The pop appears to be an analog audio circuit powering up. Apple has apparently muted the internal speakers so that the pop is not heard through them. However, headphones or external speakers will pop loudly. When mine wakes from sleep, I get a flash of a blue screen, as the screen goes dark again, I get the pop.

This is probably not broken hardware. Maybe it can be fixed with firmware, maybe not. One way to minimize it is to run the Mac's audio volume all the way up during normal use and set the external speaker's volume control for the desired volume. This minimized the audio gain downstream from the source of the pop.

I will have to retract my earlier post on this. If I turn up the volume on my external speakers and have the Mac volume near the highest level, I do get a pop. I would not call it really loud, but it is definitely there. My guess is that the power to the audio board is coming on in a surge of some sort and sending a rogue signal to the speakers.

It is not something that concerns me in any great deal, but it will be interesting to see if it can be worked out with software or if this is just a quirk of this new hardware.

My 17" iMac CD has the popping noise when it wakes from sleep, but it seems to continue on for a few minutes once it has been woken. I have it connected to external speakers but the popping noise seems to come through the internal speakers. I have also noticed the same noises when I first start it up too.

I have the same problem when I wake my 20" (early 2006) iMac from sleep. It happens not only with my external speakers (Soundsticks II) but also with headphones attached to the audio output jack. As such, it appears to be an issue with the jack itself but could be OS related -- it never happened with my prior Mac (PowerMac G5 dual 2ghz). I am going to call Apple or bring my computer in to an Apple store as I don't believe this to be normal nor acceptable. I should have waited for the "Revision B" model that will most likely be out soon.

Btw, does anyone know how to make the internal speakers work along with external speakers?
