its win 10 64. it is only the optical output that I know of the headset works and if I switch the default to hdmi sound it works to I haven't tested the other audio out ports.
The optical output works on all steam games and other computer apps like net flicks and Pandora. The only games that give me problems are DAI and Star Wars the old republic
The big oddity is that one out of 100 or so tries it will work for DAI. Star wars works more often than not.
It is not a loose cable or damaged one because If it were other programs would have the same issue and I can play music while DAI is not working.
