To summarize, in compact mode you will get the audio playing icon on a tab but it will hide the favicon in that case. In normal mode, and only if you have a small number of tabs, you will find a tiny 'PLAYING' text instead. If you hover over it, you will find the playing icon...which will have hidden the favicon then. UX geniuses with too much time on their hands.
