This is not a feature request but bug report to @Mike.
The integrated Audio Player of MRC doesn’t work for me on Firefox nor Chrome. When I load the page, the player does either not appear or plays no sound.
It seems as the server holding the audio file doesn’t give anyone/-thing access to the file. When I try to play/download the file directly from the server, I get an “access denied” information.
Maybe there should be an official place for bug reports too?
