crappy nvidia hdmi driver

so, on my htpc i wanted a strong gpu for dsplayer, which puts to shame any android or whatever else is available for kodi, in terms of image quality. however my nvidia gtx 1050 ti does not send AC3 or DTS signal to the tv-receiver connection. on the same exact system, onboard intel card sends the 5.1 signal, and also when i plug in the amd card, it works also.

does anyone have a driver that sends HDMI audio signal properly through nvidia? thanks…
