MacBook Satic Blip Sound
+* MB404/B - MacBook Black 2.4Ghz/2GB/250GB, Mac OS X 10.5 - Static noise (sounding like a pop, blip or bip) from either left or right speaker area bought new March 2008.+
I bought the MacBook Black MB404/B, 1st March 2008. No problems for about a month. Then started to display this strange static sound (as above) from the left speaker area. The sound is audible just before the start-up chime. A static blip followed by the chime. The sound will also occur just before any other warning sound. e.g. turning up volume, received email sound, incoming iChat message etc. Each sound is preceded by the static blip, followed by the standard sound for that application.
However; if the blip has just occurred, it won't do it again for a few minutes.
The static blip is also audible if the MacBook has been muted.
Also, plugging in and unplugging headphones would cause the Mac to do three static blips in concession, whilst flashing the red optical light inside the headphone port.
ATTEMPTED SOLUTION: I reset PRAM/PMU, Reinstalled the OS. Started Mac in Mac OS X 10.4 (Tiger) using external FireWire drive. No change.
16th April 2008 I had the MacBook replaced under the guarantee.
When turning it on and running through the welcome to Mac animation, the music was scratchy static sounding from the left speaker. It also made the exact same blip sound before the start-up chime. It appeared not to make the noise at first with the warning sounds, but the next day 17th April 2008 it started to behave the same way. Additionally it makes a slightly louder static sound from the right speaker area which appears more intermittent.
This appears a manufacturing defect having occurred with two machines now.
Note:It's not the hard disc, the sound of a failing HD is quite different. I originally posted this earlier at appledefects.com
Anyone else noticed or experienced this? I'm currently calibrating the new ones battery and if it still displays the problem, I think I may ask for my money back (I bought it from John Lewis:UK, who tend to be better than buying direct from Apple).
Cheers.
