Hi kevinbryn,
Welcome to the Roku Community!
Thanks for letting us know about this concern that you have with your Roku TV.
A Roku TV might mute your AVR amplifier when switching off because of a setting on the TV called "Auto Power Off" or a similar function. This function sends a signal to the connected audio device (like your AVR) to also power down, often including a mute command to prevent noise spikes when the TV shuts off completely; this can be adjusted in your TV's audio settings.
We hope this helps.
Best regards,
John
Hello,
Your answer seems to be answering a different question / thread. The question is not about a situation when the TV is switched off but instead about something that happens 12 minutes later as described.
For your information the amp does not get muted as trying to un-mute it does not work. The only solution is to select a different input source then set it back again.
Auto power-off is not enabled on the amp.
I have tried setting the TV to "HDMI compatibility mode" but it made not difference.
It is a real pain as 12 minutes after the TV is switched off and other input sources are being used on the amp, everything suddenly goes quiet and it is the Roku TV causing it to happen.
There were originally two separate threads with two separate questions, where these two threads seem to have been merged into one which is causing confusion as to which question is being replied to. Sadly neither question has been addressed and the problems continue.
The problem with the amp cutting out 12 minutes after the Roku TV is switched off is the most obnoxious one and for now I have to change to switching the TV off by removing power at the wall socket so that it goes completely dead and cannot cause these problems. No other connected device has ever done this to the amp. I shouldn't have to be doing this and hope that the next software update will fix the issue.
