Howdy,
Confirmed that if casting from cell phone YouTube app to Sonos Home Theater group that Arc and both Gen 3 Subs work. However, after messing with settings in Windows 10 / Dolby Atmos for home theater, I am unable to produce any tones via the Gen 3 Subs when setup is RTX 3090 GPU / PC → LG CX → ARC via eARC.
How do you get Windows to recognize the Gen 3 Subs?
Any help would be appreciated!
What signal is your PC outputting?
Edit.
Try running Dxdiag on your PC and check the audio settings tab.
Thanks for the reply
After running DirectX Diagnostic Tool, I didn’t see any parameter for signal; however, the Device is LG TV SSCR (NVIDIA High Definition Audio) and the driver is nvhda64v.sys version 1.3.38.40 (English).
Is there any other detail needed from this tool?
Can you please check what the audio settings are on your LG TV? There have been a lot of issues reported with LG TV's.
Sure. They are as follows:
Sound Out = HDMI ARC
eARC = On
HDMI Input Audio Format = Bistream
AV Sync Adjustment = Bypass
Digital Sound Out = Pass Through
