I am unable to hear a player, but they can hear me

I am struggling to use the audio features. I am on the most up-to-date version of Firefox. No add-ins are enabled for the roll20 site. I've tried going through all the basic steps, clearing cache, using Reconnect, etc. The players can hear me, but I cannot hear them. My audio output source is set to None and I do not have an option to change that.
