Audio or Video

I noticed that only one type of media player will work for each sermon.
In other words, I cannot use both audio and video at the same time.
If I do, only the video is embedded and there is no audio control embedded.
If I remove the video youtube script, the audio control appears.
Is this how it works?
Or is something wrong in my setup?
We need to have both audio and video available.
