Loud *POP* when using sound after sleep

I love my MBP, but one problem has been driving me crazy...

After I wake from sleep (or start up, etc.), the first time the computer makes any sound (from any application like iTunes or a system volume change, etc.), the sound is preceded by a pretty loud "POP" sound from the computer speakers (or from external speakers if they're hooked up). Then the music (or whatever sound it's supposed to be making) starts. It only does this the first time after each time it wakes up, and it sounds like the computer is "turning on" the speakers/sound output/whatever. It does this pretty loudly, though, and it's really annoying--especially because I use my computer for an alarm. Every day, I wake up to the loud *POP* followed by some nice quiet music.

My MBP does this EVERY time it wakes from sleep and regardless of what application causes the sound. I assumed that it was a normal (and very annoying) noise that was supposed to happen, but my girlfriend's new MB does not do it.

I was wondering if (1) anyone else has this problem and is it normal/supposed to happen and (2) anyone has an idea about how to stop it if it isn't supposed to happen (resetting PRAM? SMC?).

Thanks in advance for the help.
 
From what me and my other computer music friend can figure, it is Core Audio turning itself back on. I don't believe it is the internal audio card as it happens with a external sound card as well. Happens on his MBP and does not happen on my MB.

Not sure how to fix the problem though.:(
 
*sigh*

That's what I was afraid of. Thanks for the help, though. Here's hoping Apple eventually comes up with a fix.

mine doesn't do it and I don't think that's normal. You should probably contact Apple Customer Service.

Hmmm, worth a try. Mine is a C2Duo bought last December. Maybe they've fixed it for later models? When did you get yours?

I got mine in... November 2006. I've Never had that problem and i have a friend who has the same model MBP as me and he's NEVER had that problem. That's not normal and I deffinately think you should take it to the nearest Apple store.
 
Thanks again for the input. It sounds like I'm not alone, but it's not normal. I'll get it to the nearest Apple Store in a couple weeks once I'm done with finals.
