Just made an upgrade of my old GTX770 to GTX1060 and got problem. No sound via HDMI output on my TV. At the same time under Win10 everything works perfect.
I tried various models of GTX1060 and HDMI cables. v7.90.008/009/010 and builds from this tread LibreELEC (generic and nvidia) didn't solve this issue also.
Thank you in advance for any thoughts.
