Are there any tools available to troubleshoot HDMI CEC problems (other than OSMC log dumps)? I want to do all I can to make sure this isn’t an issue with my gear before I open a ticket with OSMC.
Backstory: Samsung QLED TV, Marantz SR5012 AVR, Vero 4K+. I normally turn everything on/off by suspending/resuming the Vero, but that quit working a few months ago for no apparent reason. A couple of weeks ago, volume control also quit working (audio is set for passthru to Marantz). I replaced the HDMI cables, no effect. No idea why this is happening but I can’t rule out it being a problem with my gear and not the Vero. If I had some way to troubleshoot HDMI CEC I could likely determine if it’s my gear or whether I need to open a ticket.
