However, the sound does not come out of the tv at all, only from the laptop, i tried fixing it in playback device, but there is only SPEAKERS, no hdmi option.
In control panel -> sound -> playback tab click right and mark the settings: enable hidden devices, enable disabled devices.
Now you should see all playback devices which are available and not hidden.
If HDMI/digital output is disabled, enable this and mark it as default device… now the sound should appear on TV
