Follow these steps to connect your audio/video devices to the your system:

Alternative connection method
If your TV does not have enough inputs for your audio/video devices or if you are unable to get sound after turning off the TV speakers, you can connect up to three devices directly to your Bose® system with three different audio cables.
For example, connect your DVD player to the Bose® system with an optical cable, connect your cable box with a digital coaxial cable and connect a game system with an analogue audio cable.
Note: For this setup to work, only one device can be turned on at a time.
