I set my PS3 to pcm and let it do the decoding. The only thing is, on my avr it doesn't say dts-hdma etc. It says multichannel, but the speaker indicators light up to show which speakers are active, which I already know by which track I've selected in the disk menu. My old fashioned brain can't get fully into htpc yet. Too many variables and ways to screw it up. Try pcm on the ps4 before you give up.
