The Sony STR-DH130
That's the model in question in this post?
I generate the full list of commands from that protocol and device and fired them one at a time at that Sony Receiver. What I posted above was what codes the device responded to. Unless this receiver supports codes from a different code set (Which might be possible) then they don't exist. You'd have to find a different speaker a / b hex from another model and try it.
