Linking to an audio file I get a large slightly rectangular playback icon on my course page (shown below). This graphic is way too large and the wrong shape. What I want in its place is the thin horizontal black playback line (shown below) that comes up after I click the grotesque icon. Any way for me to change the gross icon as a teacher? as an administrator? What do I need to do exactly? I want a totally customizable page, even down to adjusting the size of icons for my courses. Possible?
