popping when new sound comes through, with Bose companion speakers.

I purchased a refurbished 24" iMac in June. About 3 weeks ago I started to get this annoying popping noise from the built in speakers. I have a Music Fidelity Xcan V8 tube headphone amp connected to one of the usb port, when I'm listening to music with my Shure SE530's there is no popping noise. So I'm thinking its an issue with the amplifier stage of the iMac audio card. Which is probably built into the MB?

It is annoying and for the price of the iMac its " very annoying"

This has been going on for well over a year, and apple seems to have no interest in fixing this annoying issue. But, for the record, I've been on the list of "poppers" for quite some time.

It would be nice if there was at least an option in the control panel to not put the sound to sleep, or whatever causes power to the headphone jack to cut out.

BUMP!!! (or should that be pop). Had no problems previously in Leopard.

I didn't notice this problem when I first got my Unibody MacBook Pro(late 2008), but I had my logic board replaced because my computer would freeze randomly when using the 9600GT graphics card. Also the repair slip said they replaced my speaker!? They must have replaced my logic board though because my MAC address is different. Now that doesn't happen, but I have this pop problem. Just like everyone else it happens right before a sound is played, if no audio has been played for a while, or after playing audio after sleep. I agree it sounds like something with the audio power saver. I really wish I could get this fixed, talked with apple last night they had me reset the SMC, PRAM, then told me to take it into my local apple store. Honestly this computer has spent more time in the shop than at my house! I really wish Apple would fix this... Soon!

I just bought an iMic to remedy this popping sound w/ the Bose Companion but I can't get it to work. I'm sure I'm just not hooking thing up correctly. Can someone talk me through it? What gets plugged in where? Thanks in advance...Karen

Disregard...I found the answer. Thanks anyway! kw

I also have this POP noise on a Black MacBook under snow leopard.

Super annoying, startles me every time.

Hi, how about sharing"' your cure""
in another Post it was suggested that in iTunes the volume is set to minimal & the actual speakers volume control is adjusted your requirements.....L
