Hello everyone, I've just binned my sky TV contract after 16 years and bought a new Humax HDR-1100S (500 GB version), AND a new Samsung UE43KU6000 Smart 4K Ultra HD HDR 43" TV as well. Our previous TV was total pants and very old and did not take very well to an HDMI input, hence the reason for a new TV.. Unbelievably pleased with the picture quality after all the years of having a cack TV, we've only had this new tech 2 days and we're still learning. Sorry if this question has been asked before, I've had a little look around and can't find too much on the subject. The sound problem: Sound levels between SD channels and HD channels are at very different levels. Changing from any SD channel to any HD channel there's a big jump up in sound levels. On any SD channel the volume of the Humax needs to adjusted very high for it to be at what I would call normal level, changing to any HD channel it needs to be turned down because it becomes far too loud. We also have a Now TV box with PLEX and the sound levels while using it are normal and not low like with the Humax HDR on SD channels. We don't have any sound bar or surround sound connected, we're just using the TV speakers only. The question: Does anyone here know if there's any way of sorting this sound difference out? as its a bit annoying having to keep playing with the volume when changing channels. The only workaround I've found so far is to press the SPORT button on the TV remote which increases the volume and also the colour vibrancy. Any links to sorting it or any info Humax users have if they've had a similar issue I'd sure appreciate it.
