you can share audio clips by using file manager on your phone. navigate to the file you want to share. now press on the top menu where it says file manager and then share--> select file --> select blue tooth. you can also do sharing by pressing and holding for 3-4 sec on the file you want to share...

And you cannot watch facebook videos because device doesn't support flash version that facebook requires... solution is to install tweak flash plugin
