No sound from surround speaker pair with PC input

Hi guys,

My set-up is a Sonos Beam with 2 x Play:3's set-up as surrounds and stereo pairs. The Beam is connected to an LG OLED B7 via HDMI ARC.

The surround speakers work perfectly for all manner of scenarios including:- TV apps, Xbox, PS4, PC bit stream output, Sonos app, AirPlay, Spotify connect

The issue I have is that the rear speakers do not work for PC (PC HDMI to LG TV then ARC to Beam) output when the output is stereo PCM (such as games or PC Spotify or any app that doesn't output a bitsteam). In this scenario the sound is only coming out of the Beam.

Anyone have this issue and knows how to resolve? It maybe a limitation of ARC on the LG?
