Greetings to everybody!
My problem is that when I try to import an audio file from File/Import/Audio file into an audio track, I can’ t preview my samples. Autoplay is checked, I click on a sample, the play cursor moves, but there is no sound. The file is imported ok but you can’t choose. It started after months of use, not from the beginning of the installation.
Thanx in advance! 
Now, if we knew your used software…
Try the search function plenty of threads about just that…
Problem solved. I needed to deactivate the control room.
Thanx anyway
