The reason I asked is that I wanted to do something similar and I got in touch with DA to ask if sound was possible and they said sound was not possible. Maybe it's different for members like me in the UK. I'd be interested to know what opther feedback you get.
It is possible but you do have to go through a process. If memory serves i had to send some video/audio samples first before i could get access to the film/music category. It might be different now though. Your first comment made me think the audio wasn't working, obviously a misunderstanding on my part
