[Plugin: Audio Player] Auto imported urls don’t show up in player

I have my blog auto populating some mp3s from an RSS feed and they refuse to function with the Audio Player. I’ve formatted my feed so it formats the URLs [audio:url] and it imports fine, but doesn’t show the player. If I take the same bit of code and paste it into a new blog entry it will show the player just fine, but it won’t show up in these auto imported entries.

I tried changing the mp3 urls to be regular links, then using the Replace all links to mp3 files feature, but it doesn’t do anything for these posts either.

Anyone have any idea why it won’t work?
