No sound on HDMI 1 but on 2 and 3 it's working fine


Jul 29, 2017
When HDMI connected to port 1 - picture but NO sound. Same HDMI connected to port 2 - picture AND sound. Why? Samsung UHD Curved TV Series 7.
May sound strange, but have you tried re-naming the device on HDMI 1? I.e you can 'label' the HDMI inputs. See what it is named as, and if it is something like 'DVI Devices' then change it to DVD and see if you can get the audio back.

I can confirm this works

I had the same issue but with a Panasonic TV. I read this and in the HDMI settings, each port has "mode 1 and mode 2", I simply switched from 2 to 1 and it worked. Maybe this might help.
