Audio setup issue with PS4

I recently purchased a PS4.

For audio, I have been using either the PS4 wireless headphones, or a cheap Bluetooth speaker that I connect through an AUX cable connected to the PS4 controller.

What I would like to set up is most likely an entry level surround sound, 2.1 or 3.1.

The issue is that I connect my PS4 to a monitor that only has 1 HDMI port, and don’t quote me on this, but I believe the PS4 slim has one HDMI port also.

I have no way of connecting a speaker system to the monitor, directly at least.

How could I connect the speakers If I only have exactly one pair of HDMI ports?

Solution 1:

You can buy (at least in the UK though I assume they're available worldwide) a HDMI Audio Extractor. This takes in the HDMI signal and loops through the video signal and has a separate audio output for connecting your speakers to.

Alternatively, you could go the full way and buy a 5.1 (or greater) surround sound system which will include an amplifier which does everything for you.
