I've ran into this problem today, my video file peaks are built, but the audio will not play, when I render the file the audio is there. I just cannot get it to play during my preview.
Also maybe someone can help me with this problem, when I un-installed and re-installed my Vegas, and deleted my Sony folders. Now my project files (.veg) will not open, I get this error "an error occoured while loading the project file (project file name) An error occurred reading the file. Make sure you have read access to the file/folder and that it is not corrupted.
The files have not been moved, or renamed, the projects just won't open. I can always re-create my project, as it was just clips from my raw files, but If I could get my projects to open, that would save me quite a bit of time.
My files are .M2TS, and work fine if I drag them in, just the audio won't preview, actually, NO audio will preview, MP3 files included.
Please help me, this is driving me nuts, I have even done a system restore, to no avail.
