The ability to move checked devices to top has only ever worked on the midi outs.. and frankly should be on audio in, audio outs as well as midi ins and outs..
it has been logged as a bug (for the midi) and a feature request (for audio) for several years that i know of..but continually ignored..and now possibly even totally forgot about, but as a user with 20+ inputs and outputs is frustrating to wade through pages to check exactly what is on or off.
Perhaps its time for these both to appear in the bugs & feature request section (again)
