its really easy to do.
admin/plugins/ray/ then in the music player click setting and uncheck the "enable file saving" box, click save do the same with the pmusic player.and video player if you want to.
that stops downloads.

then you need to go to admin/page builders/ click home page and remove the music and/or video blocks from the home page.
that hides them from public view on the home page.

then you need to go to admin/settings/membership levels
and make sure the non-member see more has no music or video upload or playing permissions, just delete them on that membership level if they are there.

then make a text file called "robots.txt" and in it enter the following
User-agent: *
Disallow: /ray/modules/movie/
Disallow: /ray/modules/mp3/
Disallow: /ray/modules/music/
Disallow: /ray/modules/video/

this will stop your music movie and video files being indexed on google and all other search engines, place this file in the root of your dolphin folder
