Audio mysteriously disappeared, help?

Question

I'm new to Adobe Premiere Elements 9.  I have a file that I imported.  In QuickTime 7 Pro I had pieced together video/audio clips, but then I wanted to make a movie for a gift so I bought PRE 9.  Anyway, in PRE I clipped each snippet of video/audio so I could add transitions between them.  Now, in the Timeline window, I can see both the audio and video pieces, but when I play it, only the video plays - no audio.  What did I do??  I've check all the volume controls to make sure they are not muted and the volume is at a level I could hear.  I checked the connections and am able to play/hear music on you tube.  Thanks for your help.

Looking back up to Reply # 7, it appears that the Frame Size is not that of AVCHD-Lite, which would be 1440 x 720, IIRC.
Back to your "flatline" Waveform Display, it appears that your edited Clips have become unlinked from both the CFA and PEK files.
The CFA files are the Conformed Audio files, created when one Imports a Clip with Audio into a Project. This Conforming creates a 32-bit floating-point WAV file for editing. The process also creates the PEK files, which allow PrE to display the Waveform. Those two files will be created in the Media Cache folder inside what PrE refers to as the Scratch Disks, and located where the user directs the program to place them. After they have been created, they are then linked to their respective original Clips, in the PREL (Project) file.
Usually, if those links get broken, PrE will just regenerate the CFA and PEK files, but that is not happening to you, and you are also not getting any error messages, asking for file locations, so something is happening.
Unfortunately, you are going to have to help me a bit to try this next step, if we can. I do not have PrE 9, so do not know if it has added a little feature from PrPro. You will have to poke around a bit, or maybe others will jump in and tell us that the feature has NOT been added to PrE 9. In PrPro, one can go to the Project Panel, Right-click on a Clip, and then choose to "Offline Media." There, a dialog box pops up, asking if the user wants to "Unlink the Media, or Unlink and Remove from the Hard Drive." In our case, we would ONLY want to Unlink in the Project. Again, in PrPro, one would then repeat the Right-click, and choose "Link Media," reestablishing the link. This would cause the program to regenerate new CFA and PEK files, and there would be a little progress bar at the lower-right of the program's GUI. One would not touch the computer, until that progress bar disappears. What I just do not know, and cannot test, is whether PrE 9 has added that Offline Media feature. [Editing Offline is something more often done in a pro environment.]
There is another similar feature in PrPro, called Match Frame. It does something similar to the Offline Media. I feel very certain, that PrE (no version) has Match Frame, so we would most probably just be wasting our time, looking for it.
For some more background on Conforming and the PEK file generation, see this ARTICLE.
Good luck, and let me know about the Offline Media in PrE 9. There is a "manual way" to do it, but if the feature has been added, it solves a lot of potential issues and saves some time.
