Hi. So I am going to try and attach a PDF of my set-up. I have an Optoma UHD40 projector connected via HDMI to an audio extractor, into which goes my Sonos Beam soundbar. I also have three inputs into the extractor: an Xbox, a Roku, and now my brand new Humax Aura. Both the Xbox and the Roku display hi-def visuals beautifully in this set-up, as did the clunky old Samsung BD-8500 Blu-Ray/Freeview recorder that I have replaced with the Aura. ALl three had no problems, and the audio was great through the Beam.
I have put the Aura into the vacant HDMI input on the extractor and it picks it up, but my projector drops it as a source every 30 seconds (at best, sometimes it constantly brings up the image then loses it and goes to a blank screen while it "searches" for a source).
This is very frustrating because the few times it has held the Aura as a source for a minute or two, the Aura looks fab.
So is this a cabling issue? ie, do I need to buy better HDMI cables (fibre optic perhaps? In other words, is there something about the Aura that would require better cabling that isn't demanded by the xbox or the Roku or the older Samsung unit?
I have tried plugging the Aura directly into the projector (ie, not via the audio extractor) and the same thing happens.
I have tried a few different basic HDMIs from the Aura to the extractor. But the cable I have direct to from the projector is this one, which I thought should be OK: https://www.amazon.co.uk/gp/product/B00LPG73B2/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1
So, basically, I need a bit of help I think. Any ideas? I was hoping to have this sorted in time to record loads of Christmas stuff for the kids. But, maybe I'll have to return the Aura...
