I did note that SD channel volume can be controlled via the Humax remote and turning up the volume for that to a level corresponding to that of HD channels would solve that problem (as ridiculous as it seems to me). There still remains the 5.1 issue. For example Quest HD broadcasts Wheeler Dealers with Dolby 5.1 audio. There are other channels including BBC1 that do likewise with some programmes. Am I asking too much of the Humax? What’s the point of the TOSLINK port? It seems to be useless - I might just as well connect L and R channel audio.It's not ridiculous . Dolby Digital Volume levels can only be varied after decoding to analogue audio (the volume level is hard coded into the digital data). So your AVR can only control the volume for DD content after decoding.
Not familiar with your AVR but most have a level setting for each input.
So the box remote cannot alter the volume level of HD channels only your AVR can do this. The toslink connection is capable of 5.1 audio for standard 5.1 audio. Loudspeakers only work with analogue audio. So only the AVR has volume control.You should set up the box volume level to match what you hear on HD channels and leave it there.
Thereafter use the AVR remote. For this to work you need to turn down the TV volume and use the AVR output.
You cannot expect to use The TV volume using HDMI and the AVR using Toslink at the same time. Presumably the TV is not capable of decoding DD 5.1.
I use a 5000T with a modern Dolby Atmos high power Denon AVR and 11 speakers including Dolby Atmos. It works fine with 5.1 when present.I get your point but I’m not doing anything with the TV volume. I’m trying to control audio levels with the AVR remote from the Humax to my AVR via TOSLINK, just as I did with the Virgin Media kit. The TV is not connected to the AVR. HDMI from Humax to TV, TOSLINK from Humax to AV. Not an ideal setup, I’ll admit but there are no HDMI in/out ports on my ancient AVR. I’m just disappointed that what worked with the Virgin box doesn’t with the Humax. Perhaps I should start looking for a new AVR (Your last paragraph has made me envious.)
If the toslink has Dolby Digital audio output it cannot be varied at source without a real time Dolby Digital decoder and encoder. It has to be decoded to up to 6 analogue streams before you can vary the volume. Only the AVR volume control can do that. However you may be able to set the Aura remote to control your AVR volume.
