Turning HDMI-CEC on or off

CEC (Consumer Electronics Controls) is a way for communications and operations to occur between devices connected with HDMI cables. This feature allows for one device to control basic functions of another device, such as turning a device off or change the selected input of a TV.

To turn HDMI-CEC on or off:

  1. In the Bose Music app, tap the Settings icon icon in the upper-right corner.
    Tip: If the a different product is shown, tap the My Bose icon icon in upper-left corner then select the desired product.
  2. Scroll down to the Power section then select Advanced CEC.

     
  3. Tap the circle next to the desired option to select it:
    • On: Enables CEC (default setting)
    • Option 2: This option resolves most CEC-related issues with older devices. Try this setting if you cannot control or experience unexpected control with certain devices
    • Option 3: Use when a TV does not send the expected 'power on' command when it turns on
    • Option 4: Use when a TV does not send audio to the soundbar, or when the TV plays sound through its speakers instead of the soundbar
    • Option 5: Use when the HDMI connection to the TV is lost and sound does not return after reconnecting
    • Option 6: Use when a TV (or other HDMI connected device) turns back on soon after being turns off
    • Option 7: Use when a TV does not send the expected 'power on' command and the TV does not respond properly when turned off
    • Off: Disables CEC
