I am having an issue where the AVR is incorrectly selecting my TV Audio Input source instead of HDMI 2 when everything first powers up. This causes me to have to manually select HDMI 2 after the TV is on and warmed up in order to have sound.
Here are the details:
Under the Setup HDMI menu on the AVR I have HDMI Control set to ON, ARC set to ON, and TV Audio Input set to AV1.
I have my Comcast STB connected to the AVR via HDMI 2 input, and the HDMI output from the AVR is connected to the HDMI ARC input on my Samsung PN63C8000. The STB remains on at all times and when I finished viewing my AVR is always on HDMI 2 and I power off the Samsung and AVR.
When I power the AVR and TV, the AVR correctly shows HDMI 2 **at first** - while the TV is warming up. However after about 5 seconds the TV warms up as soon as the picture comes on the AVR switches to AV1!
It seems like the TV Audio Input setting of AV1 is causing the AVR to say "Oh, the TV is on, I need to switch to AV1". However that is wrong. I get NO SOUND that way. The receiver needs to be on HDMI 2 in order for me to get sound.
In fact as soon as I manually switch it to HDMI 2, I get sound and everything is good. But the problem is the next time I turn on all the components I have to manually choose HDMI 2 again. And I can't set a macro for the remote to switch this because its about 5 seconds after power up before the command would need to be sent, and no family members are going to keep the remote pointed at the TV that long...
If I change the TV Audio Input setting to something else, then when everything powers up the AVR switches to that setting. So this setting is definitely dictating what input gets selected.
If I set the HDMI Control setting to OFF, then the problem goes away. However that is not a viable solution, because for other viewing I need the Audio Return Channel feature. And ARC does not function if I set HDMI Control to OFF.
Ideally there would be an option I could use to tell the AVR not to auto switch. But apparently there is no way to do this (short of turning off HDMI Control, which would then cause me to loose ARC).
Does anyone have some ideas on how to best handle this? Thanks so much in advance!
