Help: No Audio when importing Quicktime movie

Hi Everybody, Windows 7 Sonar X1d 32-bit I'm having a problem. When I import a quicktime movie into Cakewalk Sonar X1d. The movie palys fine , but there is no audio with it. Even if both "Import audio stream" and "import as mono tracks" are selected when I perform the import. I have my project settings set to 48kHz/16 bit. When I import a separate audio file into the same project, that file plays fine. So it doesn't seem to be any problem with my audio setup. I'm primarily on Pro Tools now, doing some mix work for TV spots, etc. My hope was to export my final quicktime approval file from Pro Tools and import that into Sonar in order to use Toneboosters VST Loudness Meter to check the final mix for broadcast. Any help would be appreciated! C.
