Uploading files from Soundcloud

I am trying to upload files that are uploaded to Soundcloud into my Omeka site. I have put the embed information in HTML Source Editor in Title but the file is not showing up.

It's likely that the embed code is being stripped out. Go to Settings -> Security, and check to see if the needed HTML elements and attributes are allowed.

I clicked on allow all types of files to be uploaded but it's still not showing up

Just to make sure we're on the same page, there's file uploads, which refers to adding files directly to items when you create or edit the item. Then, there's embedding external items in the metadata fields with an embed code.

It sounds like you are embedding something external. In that case, on that security settings page the relevant stuff isn't the types of files to be uploaded. Instead, it's the allowed HTML, further down the page.
