I just did the 2.2 software update, from the 1.8 that came in the unit when I installed it in June. I was also not able to find release notes so I did the update hoping it would address a weird problem. It did not.
The weird problem I am having is that at one wall plate I get no audio (digital or analog, both are connected) from source 3. This source is a Directv HR20 receiver/DVR. Here is why this is weird: The audio from that source is fine on the other 3 wallplates up and running, and I have a second HR20 connected to source 2 which delivers audio fine to all rooms, as do source 1 and 4. Any body else experience any weird audio issues like this?
And by the way, after upgrading to 2.2 the 1108 router no longer routes correctly, now it passes commands to the wrong source sometimes. Once it starts, it will stay sending commands to the wrong source until you change source away and back again, but when someone else (another wall plate in use) changes source it runs the risk of messing up and sending IR to the wrong source.
Does anyone know where I can get 1.8 do downgrade back again.
