How can I change the size of the audio media icon?

I'm using audio uploaded to my library through the rich content editor. When looking at the html for flashplayer, I go to adjust the width and height but it doesn't actually show even when it is saved and published. Is there another way around this or a reason why this wouldn't be working? When I attempt to adjust the size in advanced settings, nothing shows up when published so you cannot interact with the audio.

Thanks in advance!
