I had another issue with the mac mini and opened it to fix. Now, the internal speaker is not working correctly. If I play iTunes all I hear is a muffled noise, however when I turn the volume way down on both iTunes and the mini, the muffling is gone, but the volume is way too low to listen to anything. I double checked all the wires inside the mini and everything seems to be connected. External computer speakers work fine when plugged in. I tried an SMC reset as well as opening garage band. I also updated to 10.6.2 recently and can't recall if the internal speaker was working fine after this... Anyone have any idea what is going on?
