With the addition of shortcode [soundcloud] in the WP JetPack, the Soundcloud is gold plugin breaks and all players are not available for use.
A. Overrule the JetPack [Soundcloud] shortcode (not sure if that is possible)
B. Change shortcode from [Soundcloud] to [SoundcloudGold] (with a upgrade function to modify previous shortcodes to the new one).
Hope the owner of the plugin can have a look at this, as there is no option in the JetPack to disable only the Soundcloud option.
