While you may get an answer here, you’re much more likely to get a satisfactory response on an AMD Radeon board. This board is mostly for Sonos, not AMD support.
Hi,
I’ll try the AMD forum too as that’s a good suggestion. I’ve posted this also on Tom’s hardware forums. At the moment most people replying have set up Dolby Atmos over DAC/ AMP’s and I’ve not heard from anyone with a EARC set up.
It might be that my issue is quite niche in the PC crowd so I thought to try my luck here. If I do get an answer I’ll post it here as it may help someone else.
Thank you.
As promised I found a solution. Please use the thread below from the AMD forum to save me typing everything out again.
