Silent audio clip - until I paste it to a new audio track

Often when I record an audio track, then try to play it back, it will not pay - no sound. The audio waveform is there, but nothing. When I paste the clip to a new audio track with alll the same settings, it does play. Also, often, a track will play, and then stop playing, and I then do the same - paste it into a new track, then it plays. This is embarrassing when I have clients watching this happen. Any suggestions? Thank you.


Make sure the Monitor button is disabled on the track just recorded, please.

Yes - the monitor button is not selected. No matter what I do, it will not play even tho it shows audio.
