I work for a college's computer center and we are an authorized Apple repair center for AppleCare issues. For some time I've noticed a strange sound issue when watching videos/listening to music THROUGH HEADPHONES on my MBP that was purchased in August '07. There is no sound issue through the on-board speakers.
The issue is somewhat faint, but for someone like me who listens to a ton of music, it is quite annoying.
Mainly out of one headphone (but a little in the other) I can hear a "digital" sounding interference during a piece of music that has a quiet part or something like that. It is most obvious when the only sound in the music is a throbbing bass beat or if the song is fading to quiet at the end of a song.
I thought something might be wrong with my sound port so I did some investigating. It turns out that all the MBPs with the exact hardware as me all experienced the same sound issue as me if it was running Leopard (10.5.2). I did a share drive through my MBP with a partition running Tiger (10.4) and the sound issue disappeared. MBPs running Leopard with an older hardware that mine also did not have any issues.
The only thing I can thing of is that there is some sort of driver issue related to the sound driver of the newer MBPs and Leopard.
The only reason I am posting this is because I feel like if no one is complaining about this issue, Apple won't do anything to fix it. So I am hoping that enough of us become aware of the problem, and Apple releases a fix for it.
If anyone has noticed this issue before, or does not that I've pointed it out, speak up! Let everyone know this is an issue!
