Good news. Thanks for the update. Please let us know if/when you upgrade the HDMI board and how that works out. I have been watching the used market on SP4s.
Ok, managed to get the non-working buttons on the remote working, somehow I think the configuration was not saved properly so reassinging the input sources in the WebUI and the buttons are all working now besided of course the info/OSD stuff as only the StormAudio's with the latest HDMI boards support that.
As for the HDMI board upgrade, it was about €1250 and I needed to ship my unit back and forth to France to Storm but I decided not to do it as it would not bring me much in my particular case.
What it would add it eARC, which I don't use, and also it would give me dual HDMI 2.0 outputs instead of 1x 1.4 and 1x 2.0 which also doesn't add anything for my as I only have 1 display connected to it.
Only thing that I might benefit from would be somewhat faster switching/locking speed between inputs but just that wouldn't be worth the cash for me so I decided to stick with the old HDMI board which is rock solid
