yes, I know the best / most logical way would to use a DDC from USB to optical , but I would like to use the optical input on the Ulra for CD player transport ,
and since I have nothing connected on the HDMI ARC input, started looking into "HDMI ARC extractors" - such as this
https://www.aliexpress.com/item/1005003208834036.html (HDMI 2.0band HDCP 2.2,4K@60Hz 1X1 HDMI audio extractor with ARC,3.5mm Jack & optical Toslink SPDIF.support RGB 8:8:8(Dobly Atmos),EDID,HDR10 .)

does anyone have good/bad experience with such an adapter?

That doesn't appear to output audio to HDMI ARC. It looks like HDMI is the input and audio output is either RCA, 3.5mm or SPDIF.
 
Have you thought of using PC USB output to a small DAC (e.g. SMSL SU1) with USB input and then RCA line input to your Wiim ?
