An everything bagel for the brain. Substantive, layered, well-seasoned.
Summary
The article details the author's frustration with HDMI-CEC (Consumer Electronics Control) inconsistencies in their home entertainment setup, where different devices behave unpredictably. They describe using a Raspberry Pi 4 with a $7 HDMI-CEC adapter to create a custom solution that monitors and controls CEC commands, fixing issues where devices like game consoles would wake the TV but leave the audio receiver asleep. The solution involves programming the Raspberry Pi to intercept and manage CEC signals, ensuring proper coordination between all connected devices.
Key quotes
· 5 pulledFor years I treated HDMI-CEC like a house spirit: sometimes helpful, mostly temperamental, never fully understood.
When it comes to CEC, the Apple TV handles it like a dream, but every console behaves like it missed the last week of CEC school.
They wake the TV, switch the input, then leave the Denon asleep so I'm back to toggling audio outputs manually.
The $7 HDMI-CEC adapter turned my Raspberry Pi into a CEC traffic cop, intercepting and managing the chaotic signals between devices.
This revenge tale against Consumer Electronics 'Control' shows that sometimes you need to take matters into your own hands when technology fails to deliver on its promises.
