Hello everyone!

Firstly, you will have to excuse my English – but here goes! :)

I have a PS5, an LG OLED 65CX TV and an Anthem MRX 720 receiver where the latter – as you probably know – does not support HDMI 2.1. I have connected my PS5 directly to the TV and I am able to play games in 120fps but I have trouble with the sound as the Anthem now shows PCM 2.0. Shouldn’t I be able to get some kind of surround sound in this setup?

On the PS5 – in the audio settings – I have chosen "AV amplifier" under "HDMI device type" and in the "Number of channels" section I have chosen "5.1", as this is my setup. I have also tried various settings on the LG TV in the “Sound” section but as stated earlier, the display on the Anthem shows “PCM 2.0” no matter what I do. I have naturally also experimented with settings on the receiver.

So, do you have any recommendations to the sound settings on the PS5 and the LG TV (“PCM”, “Bitstream” etc.)?

I have read of different solutions from HDFury (“Hdfury Arcana”) and Thenaudio (“SHARC EARC HDMI”) and could this be the solution?

Thank you very much in advance and best regards
Jonas

Your problem is either:

A. you have the tv connected via TOSEC

B. you have the tv connected via ARC but have the audio output on your tv set to PCM.

Since you didn't specify exactly how your tv is connected to that box, this is all I have to go with.
