nxnw:Please always post your own log. Your issue isn't related to shedrocks issue. He connects his HTPC directly to his am via HDMI. You have a TV between and want passsthrough over your TV. That's different. So you either provide your own logfile or we are out and you might have fun sovling your issue on your own. We want to help, but if you don't let us, we can't do anything. Providing someones log wouldn't help even it's the same issue, as the issue might depend on a setting you did. Don't say "I use the same settings while using OE"....provide the log or try to fix it on your own.
Sorry for not being clear. I had not linked that file out of laziness. I was trying to be helpful, by linking that apparently related file to this thread.
I intend to post my own log, but have not had the opportunity to reinstall LibreELEC and attend to this. I apologize for not getting to it yet and thank you for your consideration.
