I updated to 6.5.0 on Windows 10 but now there is no PC output anymore, only headphones. Before updating everything worked perfectly fine. Now it seems a driver issue because I do not see the DDJ-RB under "other devices" when following https://forums.pioneerdj.com/hc/en-us/community/posts/251129023-Troubleshooting-for-rekordbox-operations-with-DDJ-R-series-controllers I followed all the suggested steps but with no success. I have un- and reinstalled rekordbox entirely but that also didn't do anything.

Check that your DDJ-RB is not selected as the default audio device for Windows in the sound panel. If it is, rekordbox can't assign it for output.
I did check that and it is not selected as default. The DDJ-RB still does not appear under "other devices" despite following the suggested steps to install it.
I have tried reinstalling the driver numerous times now, still get "Error while opening DDJ-RB ASIO". The only way to get audio output from the computer is to set Headphones Output to "DDJ-WASAPI: MASTER + Speaker" in the channel output section.
