No audio when connect HDMI from laptop to TV

I connect my laptop to tv through HDMI cable to play NBA 2k18 and video is good but why does the sound comes out from laptop but not from the TV?

Open sound playback devices, and change the default playback device from the speakers to HDMI/TV

I tried that and there is no in game sound at all but when I tried Spotify it is okay. I think the prob is in game audio

Okay I just figured out the prob is the sounds doesn't come out only when playing NBA 2k18 . What should I do?
