So i started playing the TLOU2 and when i went in the sound options i noticed that the only available option was 2.0 channel, not 5.1 so i went to the ps4 sound settings and changed some things around. i changed hdmi out to optical out and pcm linear to dts and now i have the 5.1 option available in the game. I have my ps4 to the tv via hdmi and the tv to the receiver via optical cable. So my question is do i have the correct setup now or am i doing it wrong????
