MovieTexture on video files with no sound?

General Discussion

using MovieTexture on video files with no sound seems to cause nothing to be played.
No error just a log message for loadSfx failure,

:audio(error): Cannot open file: /c/Panda3D-1.9.0-x64/samples/media-player/test
.avi

.
Is there any way I can check if there is audio before calling the functions for loading audio and syncing audio and video so this won’t happen, or some way to know there is that loadSfx error log from Python?
