<score sound="1">\relative c' { f d f a d f e d cis a cis e a g f e }</score>
provides a mediaplayer sticked on the right side of the score, not aligned, not centered and when i click on it, a running blue ribbon runs at the top of the page and no sound is heard.
Media player is pointing to "https://www.mediawiki.org/wiki/File:Undefined"
Instead when I click on the score i hear the melody.
