Ur22c mix knob not working

i have been using my UR22c for a loooooongggg time, and have loved it, recently i have changed pc and have been using it fine on the new pc up until now, the (MIX) knob now doesn’t work, i love being able to hear myself when playing games, now i can’t, if i put it completely to (INPUT), i hear everything, if i put it completely to (DAW) i hear everything, it just doesn’t work… full stop :frowning: i noticed it had stopped the moment i tried downloading dspMixFx v3, i couldn’t work out where to find loopback, so i uninstalled it and returned to v2 where i knew my way around, now i cant find my way back to hearing my self, everything is the EXACT way it was setup for the entire time, Mic connected to input 1, full gain, so that isn’t the issue, headset output volume is max, so that isn’t either, what have i done wrong? note i have been using it fine on the new pc until i downloaded and uninstalled dspMixFx v3

The mix knob is not working for me either after the update.
