Maybe something to do with ARC or digital audio settings. Try tuning ARC off in the Sony
No HDMI out from 4K 85" Sony
HDMI from the Sony TV goes to a Bryston SP3 processor, but the SP3 sees no HDMI input and consequently there is no audio. All the HDMI ports of the TV seem to be inputs, even HDMI 3 (eARC). Video input to the TV via HDMI from the Ayre DX-5 DSD disc player works fine. Is there a switch that needs to be set for HDMI output?
