Thanks for the input. That's what I read but I wasn't sure since the home theater professional connected the HDMI to the receiver as well. Is there a way to get non lossy dolby atmos from this tv. I've read that you need to use the HDMI Arc port (HDMI2) to connect the HDMI to the receiver if you want Atmos but there is a degradation of sound quality. Thanks!
Thanks, I took out the toslink from the receiver and I figured out how to get sound through the HDMI Arc. Now I'm able to get lossy Atmos on my blu rays and other content that supports it.
The current problem I'm facing now is that I can't get sound when playing smart hub apps. I am using a logitech controller and when I choose the 'Watch Smart TV' function the cable tv starts along with the programs audio. When I choose a smart home app the cable tv audio remains and the smart home app audio does not come on. I'd like to use this instead of a roku since LG allows playback of Dolby Vision and Dolby Atmos in all of the content that supports it, unlike Roku and Amazon Fire Stick.
I'm wondering if you guys have experienced this or know what to do. This is what my 'Watch Smart TV' activity looks like.
1) LG TV Power On
2) Yamaha AV Receiver Power On
3) LG TV Input Smart TV
4) Yamaha AV Receiver HDMI Out
Yamaha Receiver Setup on RX-A780.
1) HDMI Out 1 - HDMI 2 (ARC) from TV to Yamaha Receiver HDMI Out 1
2) HDMI Out 2 - HDMI output from Xfinity box to Yamaha Receiver HDMI Out 2
3) HDMI Out 3 - HDMI output from Xbox One X to Yamaha Receiver HDMI Out 3
Your post doesn't make sense to me. Why would you be getting lossy atmos from your blue rays? Do you have your player connected to your TV instead of to your AVR? If connected to your AVR via HDMI you should be getting full ATMOS if it is on the disk not lossy ATMOS. The lossy limitation is only with sound coming from your TV to your AVR via ARC. (Which really isn't much of an issue because I believe the internal Netflix/Hulu apps on the LG only have lossy atmos being streamed to them anyway. Where it does come into play is if you are using the Plex app on the LG or USB connected files connected to the TV they will only play back in lossy to the AVR, vs if it had eArc then you could get the full atmos.)
Regarding your specific question, where the TV is showing your HUB program, but the Receiver is still playing the cable audio. Your Receiver input needs to change to TV, at least that is the setting for my Pioneer receiver. I believe that is your issue.
Also you need to have ARC and HDMI Out 1 turned on I would think in your receiver settings.
Edit: also adding that I have a Logitech hub as well. Is that what you have, when you say you have the controller?
Just want to say you may experience issues since you have ARC turned on. At least with my Pioneer this also turns on CEC. So when I choose the watch DirecTV activity, it switches activity to the DirecTV input, but then the damn LG 4K player or Nvidia Shield take over and switch the LG receiver input back to them. So I added a delay to the Watch DirecTV activity and switch input back to DirecTV again. In my case these two componenets, LG 4K player and Nvidia Shield cannot turn off CEC, so they auto switch input on my AVR.
