Digital out from the tv will work fine.
However, to get real movie sound you either need a sound bar, center channel speaker or similar.
Most TV's have crummy sound. However, some of the nicer TV's have some higher quality sound built in, including ATMOS. Look at the LG OLED TV's. Not cheap but amazing picture and the sound will do a decent job. I have the 65 and the sound is fairly good.
