Log in as a student. Go to any Forum. Start writing a new discussion. Verify that in the editor, you have both record audio and record video buttons. As admin, go to Admin -> Users -> Permissions -> Define roles. *Verify that the 'Record audio directly into the text editor' and 'Record vidoe directly into the text editor' capabilities are shown in the list. Edit the 'Authenticated user' role to remove the 'Record audio directly into the text editor' capability. As student, reload the start discussion form. Verify that now only the 'record video' button appears. As admin, In the course that the forum is in, go to Settings -> Permissions. Verify that the two new capabilities are shown in the list Remove the 'Record video directly into the text editor' capability from the Authenticated user role.
