I have a 17inch MacBook Pro, running FCP 5.1 and Soundtrack Pro 1.1 2 Gigs of RAM, USB soundsticks.
I cut my 90 sec. project in FCP and sent it to a Soundtrack Multitrack. It has about 12 tracks. Music, VO, Dialogue, FX, etc.
When I push play, everything starts playing fine, within 20 second this crackling messy awful sound overwhelms everything. It's not coming from within the tracks. It's global to the whole project. It seems inconsistent, sometimes it happens fast, other times I can work for a few minutes. Very very strange. It doesn't seem to be the Soundsticks, which I thought it might be because they're digital, but it happens through headphones too.
Any ideas?
