I’m using a LG 4K smart TV, using Sonos Arc as the sound output connecting via the HDMI ARC port, and I connect my PS5 to another HDMI port.
I have turned off the HDMI Device Link function on PS5
so what happened is when I connect the PS5 to the LGTV, the Sonos Arc works well for like a min, and then it will cease receiving signal from the TV and there was no sound. Then the TV will switch back to internal speaker and when I choose the HDMI ARC output again, there was no sound. I have to unplug the PS5 and the Sonos Arc from the HDMI port, then replug the Sonos Arc to the TV then it will function again. But when I start the PS5 again, it doesn’t work again.
I suspect it’s something to do with the CEC function on PS5 that confused the LGTV on who to speak to on the HDMI LINK function, but I can’t find a solution to such.
