Sound input source changes unexpectedly
If the audio you are listening to from your system changes to the audio from a different device connected to your system on its own (i.e. changing from TV sound to an AUX device), try the following:
Make sure the correct button is pressed.
Be careful to press the correct button to activate a desired command. If the wrong button is pressed, or if multiple buttons are pressed at the same time, the system will not respond properly.
In the menu of the connected device, try disabling HDMI-CEC.
CEC (Consumer Electronics Control) allows devices to send control information (e.g. power, input switching, remote control, etc.) back and forth over HDMI. CEC implementation and capabilities can vary among different brands, which can cause various control issues. Try disabling CEC in the menu of the connected device, then try again. Depending on the brand, CEC may be labelled differently in the device menu. For more info, see Names used by different brands for CEC.
Reset your control console.
A reset is used to correct occasional product issues. It is not something that a product should require repeatedly. For more information, see Resetting your product.
Reset the TV.
Electronics may need to be reset from time to time—much like rebooting a computer. Disconnect power from the TV for 30 seconds, then wait for it to start up.
The Control Console may need service.
If the steps provided do not resolve your issue, the Control Console may need service. Follow the link below for more information on how to service the Control Console. Depending on your product and region, you will be provided a contact number or the ability to setup service online.
