I have constant mic mute symbol on my xbox one s. I have confirmed head phones work and after much searching on internet I suspect the home hub may be the issue.
I have tried multiple xbox "fixes" without any luck
So I now suspect that either the NAT settings or UPnP may be at fault. I currently have a moderate NAT which I have read should be ok but UPnP unavailable. UPnP in home hub menu states that it is on
Any help appreciated !
