Pipewire Sound: Use the HDMI one instead of the default S/PDIF

Hi,
I use the Gnome DE with Pipewire for sound.
The current setup uses Pipewire through S/PDIF into a receiver for surround sound (5.1).
I have two monitors and one of them is a TV which I use primarily for watching videos etc.
The PC has S/PDIF toslink connects to a receiver for sound and two HDMIs into the monitors for the visuals.
The TV has a standalone toslink/S/PDIF connected to the same receiver for the TV audio to be fed into the receiver.
How can I use this option, i.e. the HDMI from my PC into the TV and then its audio  (through the TV) into the receiver?
Use the above approach for audio instead of the default toslink/ S/PDIF?
The audio settings on Gnome does provide that option - i.e. through the TV's HDMI for the audio, but when I switch to that option, the sound results in a continuous loud hissing sound.

I am not sure what outputs I can provide you to assist me in getting this option to work for me.
but below are some basic ones. Let me know if I yo require anything else.
