Hey gang, I just got through programming an activity for my 975 for using the tv apps and having the audio go through the preamp via ARC HDMI. In the 975 it was simple:
1. Set the AUX input on 975 audio to be "ARC"
2. Program remote activity to turn on 975 and tv, change inputs to "AUX" on 975 and "Apps" input on smart tv.
voila!

However, when I go to do the same on my 976 downstairs, you can't tell the AUX input to be "ARC".

Now I'm not sure what to do to be able to have the 976 process sound from the tv. (I'd rather not go optical or analog.)
Any help would be appreciated.
