Volume Control Issues - DirecTV

I recently purchased the Bose 300 Touch and I am unable to control the sound with my Genie Remote (RC73). I have gone throught the 66 options for programing the RC with no luck. I have connected the Genie to the TV and the soundbar is connected to the TV via an optical cable. I have the Bose control and would like to transfer that code to the RC73. How can that be done? Thank You!!
