I have recently installed a new Human HDR-1100S. Everything appeared to be working normally and I was very impressed with the new box/service. However, on some programmes whilst the picture is fine the sound is missing. Most commonly this occurs on SD channels, even BBC One. My box is connected directly to a Samsung TV Model UE48JU7500T (4k, UHD) using the original (new) HDMI cable supplied by Humax. Based on other posts I have checked the sound settings on the HDR and the audio is set to 'Stereo' as it should be.
Whilst the problem is not consistent, and mostly we watch on HD (where available), this is proving very annoying. Before I send the box back to Humax, can anyone suggest possible causes / other things to try? Many thanks in advance for any help you can offer.
