@Jason, we heard you and informed engineering when you posted the original message. We have not tested this at all, but it is on our list.
Jason, thank you for letting us know the hardware remedy. But we will most certainly look into it.
We are aware of this problem, but until we complete the feature set, we won't have a chance to look at it. We figure late Feb, or early March. We will ask you then to test for us, as we are lacking the proper equipment to fully test this.
Same issue here. Looking forward to get a solution for it too. At the moment, I have to unplug my Monument after usage, because I can't use any audio related HDMI feature while it is connected, as mentioned by Jason.
