How to get my Sony HT-CT60 Sound Bar Home Theater programmed to my GCI Cable remote?

This worked for me, but I have a Comcast Motorola DVD-R:
These are the codes for your SONY SA-CT60 Audio Device. Follow the instructions below to program your remote.
Most likely code: 30158
Others to try: 31758, 31759
To program your Comcast remote:

1. Turn on the TV or other device that you would like to program.
2. Press the TV button on your remote control.
   NOTE: If you would like to program your remote control to work with a DVD Player, VCR or Audio device press the AUX button.
3. Press and hold Setup until the red light blinks twice, then release Setup.
4. Enter the first code for your device listed above. If you perform this procedure correctly, the red light will blink twice.
   NOTE: If you enter an invalid code, the red light will display one long blink and exit the programming mode. Repeat steps 2 to 4 with a valid code.
5. Aim the remote control at your device and press Power once (press the Play key for devices that don't have a POWER button). If the TV turns off, make sure that the VOL+/- and Mute buttons also work. If so, you're all set!
6. If not, repeat these steps using the next manufacturer's code (you may need to try several codes to find the one that works).

The 31759 worked with my HT-CT60 soundbar and my Xfinity silver remote. Thank You!
