I just purchased the new Roku Ultra and a Nakamichi Ultra 9.2.4 Soundbar. I have the Roku connected to the soundbar and then the soundbar connected to the old 2008 Samsung LN52A650 TV.
I had it paired to the TV and it was working. The Power button turned the TV Off and On and the volume controlled the soundbar (I assumed through HDMI-CEC) This worked for several hours and has now stopped.
When I go back to configure the remote, I now cycle through all of the Samsung Codes and the sound that is supposed to turn off when the proper code is selected never stops. It then says it is not compatible with my TV.
Any idea why I had it working initially? It it possible that the Roku does not have the proper IR code for this 2008 52" LCD TV?
