After waking from sleep, the first sound played has a couple seconds of static in it. It is fine afterwards.
Can anyone try this that has a new Penryn Macbook please:
1) Close lid, put to sleep.
2) Wait 5 mins or so
3) Open up/wake up. Do something that makes a sound (start iChat, go into sound sys prefs and play an alert sound, anything)
Listen on the left speaker for static for a couple seconds with the sound.
Thanks for help!

Thanks richwig83, if you can wait a little more than 5 mins. If I don't wait long enough it will not happen I just discovered.

The sound hardware goes to sleep (turns off) to save power when not in use or when the machine is asleep. The components in your system might be slightly off, causing static when the hardware wakes up. There used to be a preference pane that played a silent sound to keep the hardware always awake (search Versiontracker), but its disturbing that this old bug may be rearing its head again in the newest machines.

Yeah that's what I figured, but that means that it is a hardware defect? On all? Just mine? Who knows. I don't think it is worth trading the machine in for though. I lucked out with the display, I got a panel that does not exhibit the dithering problems much). An I am not sure it's worth having it opened and parts replaced either. It's annoying to have the problem for sure, though. It does only happen once on wake up for a second or two.
Can anyone with a NEW Penryn MB try this?
