    Hi everyone, sorry if I did anything wrong with the way I posted this, i'm completely new to posting on forums.

    So this is my problem, and it's a big one. Prepare to be extremely confused because I have never even heard of this problem before and I found no articles that even looked close on any websites.

    I have a Macbook Pro 15 inch Penryn 2.5ghz intel core 2 duo, 4GB RAM, 250GB HD, (early 2008 model), running OSX Leopard. Since the day I got it (about two months ago) I noticed that the internal speakers were very bad sounding and had absolutely no bass. I assumed this was just because the macbook pro has terrible speakers and all of them were like this. I quickly plugged it into my desktop speakers, and it sounded alright at low-normal volumes on some songs, but I soon began to notice some distortion. I realized that this distortion was happening in all of my music, and it was happening more the higher I turned the volume. I foolishly assumed that my right speaker was blown or damaged (as it seemed to be where most of the distortion was coming from), so I purchased a new 2.1 speaker set. The SAME EXACT thing happened.

    At this point in time, I had already installed Windows Vista Ultimate on a seperate partition of the hard drive with boot camp. I used this only to play games, and I never played these at high volume, so I assumed that the sound quality was also bad on the Vista side, but never noticed in much because I only use the Leopard partition to play music and watch movies.

    Eventually, I tested my macbook pro against a friends macbook pro with the EXACT same specs, playing the EXACT same song (Arcade Fire; Keep the Car Running) on both computers. I tested them both with the internal speaker, as well as three different external speaker sets, and determined easily that my macbook pro was distortiong the sound on both the high and low ends extremely, and my friends was playing it perfectly. From this, I deduced that my macbooks sound card must be damaged or problematic in some way and I would have to get it repaired.

    Now the wierd part. I just tried playing the exact same mp3 on the Windows Vista partition of my macbook pro, and there was NO DISTORTION WHATSOEVER. Is this a problem with apples drivers for Leopard in my computer? Why would Vista sound good and OSX sound horrible on a macbook pro?

    I am so confused, especially because as far as I know there is no way to update or change the audio drivers on the OSX partion, since apple just assumes their drivers work.

    Any help or input anyone can give would be greatly appreciated! thanks in advance!

    This seems like a very strange problem. Definitely, get it into the apple store and they'll replace it.

    My internal speakers work perfectly, but I have the same problem with my headphone jack.
    I went in, and they fobbed me off

    that would either be the headphones or the jack itself
    try again and go back, sometimes it's just luck of who you get

    I'm pretty sure it's the jack. The thing is, the guy used some headphones which didn't cause the distortion. The problem is that (I think) they were horribly expensive ones.
