Newly recorded region will not playback

[teacherman]

Running PT 8.1.1 on Mac OS 10.6.8

A month ago I recorded a single VO on a mono track. No plug-in or automation used.

Today, I overdubbed a new line on the same track (punched In)

The old audio plays back fine before it reaches the new audio's region. But when the playhead rolls over the new audio's region, there is no audio heard. Once the playhead rolls past the new audio region, the old audio can be heard.

So, I thought maybe the track itself had been corrupt some how. So, I created a new track and copied-and-pasted all the audio onto the new track. But, the same phenomenon still occurs

Please assist!!
Thanks

Have you tried reimporting the audio region? Perhaps even going to the Audio Files folder and re-naming it and then import it into the session.
