Got it - thanks MarsmanIt's a dual purpose 3.5mm connection that is selectable between 'line out' and 'optical out'. There is another for 'line in' and 'optical in'. For those who want to use optical, they'd use a mini toslink cable. Some sounds cards have same connection, such as Xonar D1/X.
Yamaha RX-V373 fed via optical from onboard soundcard (I was using HDMI from the 5700 XT but as it detects 2 screens it would not ramp down the card when idle). Speakers are Wharfedale Diamond 220's. Headphones: AKG 712 Pro with a ModMic 4 with the mic using a cheap USB card, JVC HA-RX900 (modded) closedback. No filters, surround processing or anything added on for gaming. Sounds great to me in games and for music/movies.
The AVR was surplus after going Atmos on my home theatre.
How would you rate the 4xx? Have heard they can sound good, but mixed qc/comfortSchiit Fulla 2 > Hifiman HE4xx
SMSL SA-50 > Dali Spektor 1
I'm tempted to add the Beyerdynamic DT177x GO, all the reviews for them are glowing and it would be nice to have a choice between open and closed back.

Heh I'm using the same amp (also after upgrading the AV amp in the living room), the same speakers and switched from HDMI to optical for the same reason
