Smule oembed help

[[Member gash…]]

Trying to setup auto-recognition of smule recordings on a WordPress site and I've used Smule's instructions but nothing seems to work. I can't seem to figure out how to get this oembed code to work on my site no matter where I put the code. I'm very new to PHP and am just trying to find step by step directions. Frustrated that this isn't working. Any help would be great!

Smule's instructions (and a link to them) are below:

From their website:

 

Yes! Smule recordings support the oEmbed format, which is supported by WordPress. To enable Smule embeds on your site you will need to add Smule to your embed whitelist by adding this line:

<? php wp_oembed_add_provider('http://www.smule.com/recording/*', 'http://www.smule.com/s/oembed'); ?>

 

Is this what Sing Salon uses? Or does this need updating?

I’m not sure this is still working. The oEmbed endpoint returns an error.
