Audio Alignment not accepting any tracks

I’ve exhausted the usual restart etc. The audio alignment panel will not allow me to choose any track for either reference or target. There is nothing on the tracks to prevent the use, that I can tell. There is no lock, it is in regular tempo mode and it is all just one long 2.5-minute take.
Any ideas would be great. I’ve got a client breathing down my neck to finish.


Audio Alignment doesn’t accept tracks, but Audio Events. Please make sure an Audio Event is selected.

Be aware about the difference between Audio Event and Audio Part, please.

I had the same problem. The quickest fix is to “dissolve part” (Audio Editor) and reselect it again.

Thank you Martin and Raynaldo. I think it will be under control now.
