The last few days I’ve searched the forum and web but could not find a matching issue I have.
The setup:
RPi2 connected via HDMI to Sony TV
TV connected via HDMI to Onkyo receiver
Sometimes I use only the TV output and leave the Onkyo receiver off. When I switch the TV input to OSMC the audio output should be honored. This setup worked while I was running the release candidate version (2015.12-4) of OSMC. Recently I installed a fresh copy using version 2016.02-2. Since the fresh install, when I change the TV input to OSMC, the screen is dimmed (idle) and when I use the remote control OSMC awakes (just to illustrate behaviour I see). At this point the Onkyo receiver is turned on (which I don’t want).
Note that the receiver is not turned on when I reboot OSMC, this only applies when switching TV input to OSMC.
When I disable CEC it does not happen anymore but disables also the remote control functionality.
How can I prevent OSMC to turn on the power of the Onkyo Receiver?
After some more investigation I come to the following: When the TV input is changed to OSMC, the power of the Onkyo is toggled, regardless of the dimmed screen. The audio output is not changing, so the audio output is going through the TV speakers.
The HDMI settings on the Onkyo Receiver are:
HDMI CEC (RIHD): On
HDMI Through: Automatic
HDMI audio output (main): Automatic
Audio Return Channel: Automatic
LipSync (Synchronize audio and video data): On
The HDMI settings on the TV are:
HDMI Control: On
Automatic Poweroff: Off
Auto tv on: Off
HDMI devices:
Recorder 1: HDMI port 2: Kodi
Audiosystem: HDMI port 1: TX-NR626
The setting “Wake devices when deactivating the screensaver” is turned off.
I disconnected all devices and then started adding them all back in. The problem was chromecast all along. Removing chromecast sorted the problem. Now I have to figure out what’s up with chromecast…
Thanks for the link, I reattached all cables without solving the issue.
The other HDMI devices are a amino settopbox (from TV provider) and a Sony Blu Ray player, both connected directly to the TV so it is not necessary to use the Onkyo receiver when watching TV or movie. I also tried a configuration with only the TV, OSMC and Onkyo but using this combination the Onkyo receiver power is still toggled whenever I switch the input from TV to OSMC.
