Quick head's up, I know Soundcloud links are not working suddenly. Looking into the issue. Update: Looks like Soundcloud's completely changed their embed system, so now I've got to make some weird workaround to make it work. No ETA on fix. Update 2: Uh... this one's going to be a mess. Going to basically have to implement an oEmbed. YAY! Update 3: Good news: Written some PHP code that handles the oEmbed. Bad news: Having trouble getting it hooked into XF's callbacks. Almost there... Update 4: SoundCloud is fixed. You're welcome.
