The HUAWEI Vision's digital output mode is hidden by default. To enable digital output, perform the following:

1. On the HUAWEI Vision's Home screen, go to Settings > Sound > Output and press the Left or Right arrow button on the remote control to select S/PDIF or HDMI (ARC).

2. On the Sound screen, select Digital output and press the Left or Right arrow button on the remote control to select a mode you'd like to use.

When the digital output is set to S/PDIF, the current settings will be automatically saved. After the HUAWEI Vision is restarted, the audio output mode will still be S/PDIF.
