I have my card connected to a Receiver (Yamaha) and from there connected to my TV through ARC, through HDMI.
9 hours ago everything worked fine sound wise. Then I turned my TV off and went to bed, leaving the PC on to complete a download over night.
8 hours later I wake up, turn on my TV and the sound from my HDMI no longer works... The sound from the DisplayPort to a PC monitor works fine.
I've reinstalled all the latest drivers from scratch. Didn't work.
I've tried to switch HDMI cables, Didn't work.
I've made sure the Receiver works. It does.
All drivers on my PC are up to date as far as I can see.
The small display on my receiver no longer shows the Speaker Icons on the HDMI port the PC is connected to. Switching HDMI connections on the TV and Receiver does nothing, the speaker icons are still missing, my PS5 Arc works fine on all HDMI ports on the receiver.
What to do?
