rnranimal, did you split your audio into 6 separate mono tracks? That's what I'm trying to do... the only program I can find that'll open the FLAC is audacity. It does open it as 8 separate mono tracks (mine's from a 7.1 DTS-HD track) but I have no way of knowing which track is which. Center, front left, front right, LFE, etc.
Any suggestions?
