Denon TV Audio Switching [3 Easy Solutions]

The major factors responsible for the random switching of Denon TV audio and their effective fixing ways are the following:

1. HDMI Control Turned ON in TV and Receiver

If the HDMI control is turned on in your TV and Denon receiver, then you can experience your Denon receiver switching inputs. Due to the turned-on HDMI control, the AVR likely thinks that the user wants to hear from the TV source.

So when you power up your TV and Denon receiver, it keeps switching the audio. The On HDMI CEC feature is the major reason why the Denon receiver randomly switches inputs.

The CEC (Consumer Electronics Control) is the HDMI standard’s recent addition. This feature allows signal control from one device to communicate with other devices. Unfortunately, when this function remains On, your Denon TV audio keeps switching.

Solution:

Inspect your TV and Denon receiver’s HDMI control option. Next, follow the manual’s configuration setting and set the HDMI control off.

If your Denon TV audio suddenly keeps switching, at first, go to your TV menu. Then check the HDMI- CEC features and ensure it is in the Off position.

2. Bad HDMI Cable

A faulty HDMI cable is another culprit for which you encounter your Denon TV audio switching not working issue. The HDMI cable goes bad for the following reasons:

  • Cable’s physical damage
  • Damaged internal wiring
  • Extreme power force shearing the HDMI cable into two
  • Too old cable

Solution:

Whether the HDMI cable is physically damaged or its internal wiring gets corrupted or cables shear into 2, the only solution to all these is to replace the HDMI cables. To replace the cables, follow the easy steps below:

  • Unplug or turn off your Denon receiver
  • Removed the damaged or malfunctioning HDMI cables
  • Put back the new HDMI cable
  • Make sure the wires are seated and fitted correctly in place.

After replacing the old aged and faulty HDMI cables, you will get the Denon best sound mode for TV.

3. Faulty HDMI Devices

The malfunctioning HDMI devices are another factor for which your TV audio signal keeps switching.

If one of the boxes (Apple or Sky) becomes defective, it will conflict with the HDMI control. The cheap Google boxes and older Sky boxes are the culprits which disable the device’s HDMI control.

Solution:

Test each HDMI device by unplugging it each time. Make sure the Apple or Sky boxes and HDMI control are not conflicting.

Replace the old, aged, cheap, or malfunctioning skyboxes to prevent the HDMI control option from disabling on the device.
