I am using quiz combined with audiofile. Whatever possition I tried to set and audio, audio was not playable after click on the button "Promíchat otázky" (en: Mix questions probably). You can see it and test it on this page: https://cs.wikiversity.org/wiki/Ital%C5%A1tina/Materi%C3%A1ly/Slovesa_%28it_x_cs%29/10_nejpou%C5%BE%C3%ADvan%C4%9Bj%C5%A1%C3%ADch
