Audio files are importing without sound

When I try to import a sound clip, it always shows up blank. There is no sound, I can’t adjust volume and even the waveform is missing. I have updated my drivers. I uninstalled and reinstalled the program. Restarted my computer. I have no idea what is wrong. I need this project done in a week. It’s really important.

Is the sound clip inside the Audio folder inside your project? Is this sound file correct, i.e. can you play this?
Do you have QuickTime installed? SBP cannot work properly without it.
I noted that in general, imported sounds do not show the waveform until the project is saved, closed and restarted, at which time it generates the graphic.
