That RAAT__OUTPUT_PLUGIN_STATUS_FORMAT_NOT_SUPPORTED is the playback engine getting an error from your audio driver saying that it can’t get the driver to play 48khz/24bit for some reason.
You will have to tell us a lot more about your audio setup, including driver information, if things ever worked, if any other software works or doesn’t, what formats play or don’t play, etc…
