I hear audio but it doesn't appear on audio track

I captured two clips with Vegas (analog) and placed them both on the timeline. When I play them I can hear the sound, but the audio tracks themselves appear empty (e.g., no squiggly lines in them). Any suggestions?

Either the volume is so low, the is not much of a waveform, or Vegas did not build the peaks. Check Options>Preferences>General>Draw Waveorms and frames in events.

The volume sounds pretty decent to me, and "Draw waveforms and frames in events" is already checked.

Does it say "Peaks not available"? If so, I have had this problem too from time to time, but I don't know what causes it. Anyone?

Any chance you deleted the .sfk file? That is the waveform.

You can try regenerating the waveforms by hitting F5.

This may be too obvious, but perhaps you have to scroll down on the tracks?

Solved the problem. I right clicked on the audio track and selected "Properties". I then checked the "Normalize" box and recalculated, and the waveform appeared.

Actually you simply pointed to a problem rather than solving it. If you need to normalize and only after see the waveform, either Vegas burped or the audio source may have been weak or Vegas didn't process it correctly. This is what I'll call a 'semi-bug'. I've seen it before, others have reported it. Trouble is, I can't duplicate it by doing X,Y, Z. It just sometimes shows up.

What i've noticed, and this seems to be pretty repetable, is that if you normalize before the waveform has finished drawing then you only get a straight line and no volume. You have to un-normalize, then normalize again, then recalculate to get the audio back.

Hmmm... interesting. I'm not seeing the same thing and I always wait till Vegas gets done building peaks before I do anything. Strange. It just seems some audio files are 'flat' looking with no waveform peaks or hardly any, even if you zoom in, yet the volume is fine, sometimes even going in the yellow or red, so plenty of signal strength.
