No TV Involved at all. No HDMI,
I have a Project CD player plugged into Sonos Amp. Thats all.
The following remote controls the CD player using IR.

When I go to train the AMP to use the volume control buttons it does not recognise the buttone presses (but it does recognise that it is an unrecognised remote to begin with

Does the SONOS amp not have the ability to register some IR codes?
