If I understand correctly, your problem is with playback while in the editor.
Am I correct in understanding that the source mov file plays ok in a regular video player (mplayer,etc)? If not, your problem is in your source, not cinelerra. Try zooming in on the time line. You should be able to see the video frames and audio soundwave. For the clock and clapper you mention, I would expect to see a sound 'spike' at the appropriate spot on the audio track directly below the appropriate video frame. Just because the sound doesn't sync up with video in the edit mode, doesn't mean the final result will be out of sync. Render the project and then try playing the result. I suspect the result will have good sync. If the source file plays ok, then perhaps you can make use of cinelerra's background rendering option to help with the sync problem. To turn on the background rendering, click on Settings>Preferences>Performance Select the Use Background Rendering button. Setup a directory for the output for background rendering. My system uses /tmp/cinerender/ - note the trailing slash on the directory name. This will place the jpg files created in a directory which is easy to clean up later. You will have a separate jpg file for each frame of video - this can take up a lot of harddrive very quickly, so make sure you clean it out once in a while. Click on the 'wrench' to set up video rendering quality. I set mine at about 35 to allow faster rendering with lower quality. It speeds up the background rendering process and keeps the file sizes down some. This setting is only used for background rendering, not final rendering, so it only affects the preview you see in the compositor window. If you're doing some more intense filtering, color corrections, etc, you may want to set this up to make sure you're getting the results you're looking for. I've found that background rendering helps when previewing my video as it seems to have less delay loading the video frames while playing in real time. Allow the background render bar (the red bar between the time marks and the top track) to progress past the point you want to look at before trying to play. I've found that the video will usually sync up exactly with the sound after this. Note that any changes to the clips may require cinelerra to re-render the files, so allow time for this, watching the progress bar to see which parts of the video are ready to preview. The background render start point can be changed by clicking on Settings>Set Background Render to move the start point to the current edit point. That way you don't have to wait for the entire previous part of the file to render to get to the point you're working on. Good luck!
