Those types of links are not supported for soundcloud only https://w.soundcloud.com/player/?url= [nofollow]
As they do not have enough information in the url to auto generate the embed code.
Okay thanks for the additional information. Just for documentation purposes if others have the same question, in order to embed Soundcloud with the mod, your steps are to go to the track you want to share, use the embed share option, there is code that you need to derive the url from, it will look like this when displayed within the embed code:
https://w.soundcloud.com/player/?url=https%3A//api.soundcloud.com/tracks/944619253&color=%23ff5500&auto_play=false&hide_related=false&show_comments=true&show_user=true&show_reposts=false&show_teaser=true&visual=true
You need to modify the characters after the second instance of https from %3A to : and then chop off all the extras after the track number so that it looks like this:
https://w.soundcloud.com/player/?url=https://api.soundcloud.com/tracks/944619253
Obviously not an easy thing to explain to basic users of a forum, but at least I can let them know it is an option. Thanks again for your guidance.
