Getting Dashplayer to work with Audio module nodes

I'd like to get Dashplayer to work with my existing nodes created by the Audio module. I've confirmed that I can actually play files from the website by changing the $params['playlist'] to be $params['file'] and passing an explicit file name. However, I can't get a playlist to work.

I've plugged my view name into the dashplayer.getView method on the service pages, and I seem to get a complete audio node object. That's surprises me because I would have expected to just get the fields specified in the view, but it also suggests that dashplayer is tightly coupled to the way files are attached to nodes.

In other words, is it true that the only way to build a playlist with views is to use the content type exactly as described in the instructions, i.e. with the audio file attached by the upload module? If so, that would severely limit the ability of dashplayer to cooperate with other modules or other mechanisms for managing uploads.

If not, is there a way to configure my view so that it works?
