This HDMI audio extractor worked perfectly for me with a Topping D90SE + PRE90 + EXT90 combo. It seems to be available on Amazon UK but at nearly twice.
As another data point, it also works great with an SMSL SU-9n DAC. When using this HDMI audio extractor, I am able to turn the DPLL setting down to 4 (default is 7). My LG C9 OLED requires the DPLL be turned up to 11 to prevent the sound from cutting out.
