Media player uses wrong discovery prefix

[sophof]

Hi, I noticed I no longer had a media player. Some digging in the MQTT topics showed me that the whole topic didn't exist. Changing the user to an admin user created a new topic hass.agent and under it a media_player and a devices topic. It wasn't hard to add this topic to my MQTT ACL, but the issue is that home assistant won't pick it up because everything else is under another topic. Can you please fix it so that the media player also uses the prefix I set in the configuration?
