some of my vocal audio tracks not playing back...help

[albee1952]

Things to check:
1-are the tracks made inactive? Make them inactive and then active.
2-is the track muted or set to Input(the green I button)?
3-is the waveform itself muted(Ctrl+M click on a clip to mute and unmute).
4-is the waveform colored or grey(if grey, see 1 and 3)
5-change the track output to any stereo bus and then back to your main outs(I say stereo bus so you don't lose pan settings)
