Audio device remote control scanner ng - DirecTV

Good Morning!

i received a Sanyo sound bar for Christmas. When I attempt to add the sound bar to my remote
menu/settings and help/settings/remote control/program remote/program audio device I cannot find my model number (of course--69 Sanyo models supported + 11 generic codes and still can't get the remote to function

is there a way to manually "teach" the remote the codes? Is there a way to update the receiver with new codes?
