Is it possible to make a Slidecast work properly (including audio) in LinkedIn?

I have a slideshare.net account that is linked to my LinkedIn account. I created a slidecast (timed the slides to the audio, etc.), but just the regular slides show up in LinkedIn. I was hoping the LinkedIn app would be able to show it as a true slidecast, not just a few powerpoint slides. Does anyone know if what I am asking for is supported?
