I have a QN90B and just started having sound issues with external devices.
Everything was working fine, then one day we turned on our Xbox and no sound. Then I realized no sound was coming in from external devices.
I have an Xbox, Nintendo switch, and Firestick all connected via HDMI. I also have a K450 soundbar connected via the EArc HDMI port. Usually we use the soundbar for all audio.
Currently I can hear no sound from any external device, through the soundbar or TV speakers. This setup has worked just fine since I bought the TV, and has somehow just stopped across the board.
Anyone else experience this? My TV is literally less than 1 year old.
