So I've just encountered the strangest series of issues with iTunes. I took over this computer from another employee at my work last week. Ever since I performed a few maintenance tasks (nothing that would cause this kind of issue) and cleaned up files and programs, iTunes has been flipping out. It has been crashing approximately once an hour, sometimes more often, and sometimes while I'm not even at the computer. It happens in the middle of songs and there's no common event that's bringing it on. As far as I know, this was not happening to the previous user. Today, iTunes would stop producing sound every so often (even though it appears to be playing and the volume is unchanged). Sometimes trying a bunch of different songs will fix it, usually I need to restart the program (or wait a few minutes and let it crash itself like a good boy). Now this is where it gets funky. A little while ago the audio started to fluctuate. The volume goes up and down all on its own at various speeds and to various levels. Neither OS X's volume nor iTunes' volume control are moving (that would trip me out, though). I've restarted numerous times since it started crashing and once since it started screwing with my volume, and I've reinstalled iTunes. This is amusing to an extent, but I can't work without my music! The computer is a Mac Pro (2x2.66 Dual Core Xenon), running 10.4.11 and iTunes 7.6.2. So, any ideas? Your input is appreciated!
