How to output the sound?

[◄Chuck►]

The speakers must be plugged in directly where they belong, cause that Creative box will output an amplified signal (!). If you connect something else there, you will most likely damage or destroy it.

I have another simple solution though. Let the sound go through the display. Just plug the green plug (from the speakers) into the (black) headphone jack on your monitor.
Ensure the volume control on the display is set to zero and then slowly increase it. Don't put it too high or you will get some bad clipping and cracking sound.

Like this:

So the PS4 sound will go through the HDMI into the display and then via the headphone jack into the speakers. Obviously, only the front speakers will work then. If you want a better solution then you will indeed need some additional hardware.

Do you want your PC sound as well on the speakers?


Edit: Example hardware you could use to get 5.1 sound:

Another option would be to get a speaker system with some sort of digital input.
