I picked up a C2D mini and got it in the mail today, everything worked great, so I went ahead and put in a 500GB internal drive to replace the small 80GB standard one. However, when I finished putting everything back together and started it back up, I noticed there was no sound. Sound still works through the headphone jack, but not the internal speaker. Additionally, booting the old drive through USB shows it's not a software issue from the new install. Is there a connector for the internal speaker that I may have inadvertently disconnected? I don't even know where the speaker is located, so it's kind of hard to know where to look. Anyone able to help me out? I tried reseating the ribbon cable which I thought was for the audio board, but that didn't change anything, and I'm about 99% sure it's in properly. If I go into the sound settings in the system preferences when the headphones are unplugged, the option is there to play sound through the internal speakers, but obviously nothing happens. Additionally, the line in tests fine as well, so it doesn't appear to be soundboard related.
