Dropped files into tracks, lots of dots and file description (song and track name/number) prefix the audio file, waveform loads but does not play audio, no sound is generated. I could probably deal with the track alignment if the audio played,...WTF?

Thank Kev for the clarification but I'm totally groping at straws here. 
I wish a few more folks would offer something to the OP. 
And from his last post it looks like it's a big mess somewhere. 
 
OK so to test if this is just not possible a corrupted project. 
Import any  wave or Mp3 file and see if that plays/
What happens in this project if you record a new track? 
 
There's another thing other people talk about that I've never done and that's  the Aud ini file

So I dropped a wav file into an empty track, did not play back.
Recorded a new track, audio file waveform showed up in track view, no sound played back.
Opened a new project, dropped a wav from non working project into track, played back OK,
Went to advanced settings in options and reset aud.ini, no change, audio files didn't load, new track didn't play back.
Looks like something is corrupt somewhere. Have so many EQ and plug-ins in original project, stand to loose all that,......CRAP!

If CWAF says the files are orphaned, and the project doesn't prompt for them, then I think they must have been deleted from the project before it was saved. Random corruption would not have produced such an orderly and complete disassociation of all files from the project. And I'm guessing there's a good reason why tracks with re-imported audio are silent. Can you share a copy of the project file without audio somewhere?

Can it be sent to you as an email attachment, and which file exactly?

You can send just the CWP file,, they only contain the midi data and project settings. 
Do you use drop box? 
I agree with Dave about corrupted files. 
And your test now points to an issue with audio playback. 
This is another long shot, but did you check your Master output? 
If you insert a soft synth, like TTS-1 and play midi or trigger sound from the GUI do you hear that? 
Do you hear the metronome? 
Did you try bypassing all effects. 
When you imported a fresh wave file did you put it in a newly inserted audio track that is output to your master buss or directly to your audio interface?

 
 
Do not hear the metronome during playback, changed output assignment (don't know why it changed?), now hearing audio tracks that were dropped onto track view.

 
Why can't I share this dropbox link?

PM one of us,you need over 30 posts to post links or pictures. 
My e mail is on my web site too. 
 
Did you check your master outputs are going to your audio interfaces outputs that your speakers are running from. I've had no sound and it was because my outputs had swapped over to SPDIF. 

I've PM'ed you Johnny, let me know if you got it
