DDJ-FLX5 No sound (Win)

OK! Sooo after a whole bunch of uninstalling devices and doing every single suggested fix over and over I finally got my DDJFLX4 to work in Serato Lite

i.e no midi light, responds in Serato and successfully loads and plays tracks without “connection” or “permission” messages.

..but no sound from RCA > speakers. I have sound in headphone cue bur cannot get output.

I’ve got the sound devices set to speaker/mic (Realtek)

Any help is greatly appreciated!
