Anyone not getting surround sound with PS4?


I was playing NBA 2k14 and noticed the sound was low. Then noticed the sound was only outputting to 2 speakers. I tried the menus in the game, then the settings for the PS4. I tried another game (Resogun and Netflix but I still only heard audio from 2 speakers. No sound from the center and rear speakers. I plugged the same HDMI cord into my PS3 and surround worked fine. I have the PS4 audio setting on Primary Output Port to HDMI and Audio Format(Priority) to Linear PCM.
