Cheap knockoff CCwGTV remote specifically won't IR control old Yamaha amp's volume
The original Google CCwGTV remote's side buttons controlled the amp's volume fine using IR (it does not have HDMI). Set up once years ago.
Lost it and bought a replacement cheap copy remote from Amazon, it looks exactly like the original. Set up fine. I have cleared and re-run through setup, selecting the IR devices from scratch.
- volume and mute buttons will control the TV's volume ok
- power button will control the amp ok
- volume and mute buttons will not control the amp's volume on any of the 5 codes
- volume buttons are emitting some IR signal as it can be seen using a phone's camera
Any suggestions?
How is this even possible? The volume buttons do emit IR, and in the case of the TV it is the correct IR, and the Yamaha amp's code for 'power' works, and the Yamaha code for volume used to work when set up years ago on the original remote.
Have Google removed older code sets?
Can this cheap knockoff remote somehow not emit just some codes properly? (but still emit something as I can see it on a camera)
