Here are a few things to try. We have included complete troubleshooting below, and we apologize if any of them are redundant to what you have already done in this situation.
The automatic on/off link between the Bose, the TV and your BDDVD player is likely being accomplished by HDMI CEC rather than by IR control. This is a very simplistic feature that turns all devices in the chain on or off as a single machine. It cannot be custom tailored to only turn on only the selected source or something similar.
Because the Cable box is not automatically responding to the CEC integration, we can only use IR signals to control it. This means that it will be necessary to use the Source Power button to turn that component on and off.
Thank you for your question.
