If you're using playbin2, wait for the ASYNC_DONE message on the
pipeline's GstBus, then do:

  int num_audio;

  g_object_get (playbin2, "n-audio", &num_audio, NULL);

If you're not using playbin2, you need to tell us what you are
using/doing instead, because without any context whatsoever we can only
guess.

 Cheers

Well look at what playbin2 does and implement this yourself. Allthough
if you already use filesink!decodebin!xvimagesink you can also use
playbin2. Finally, I am not sure why you can about audio, if you don't
use an audiosink to play it.
