PS4 is set up via HDMI and Linear PCM through a receiver, same as my 360 and PS3. Had the same setup for years and the sound has always been fairly comparably and fine across PS3/360. PS3 would usually give me slightly clearer, louder audio, but still.
With PS4 though, I'm noticing the center channel audio is a bit scaled back and the bass is kind of ridiculous. Best example I've found is the first boss battle in Resogun. Overwhelmingly loud bass, even if I all but mute my subwoofer. The music in NBA 2K14, while not as ridiculous as the bass in Resogun, was also very bass heavy.
Killzone Shadow Fall seems fine though, great sound design.
Anyone else finding this to be the case with their audio?
