ANA_SCART
SCART I²C programming (matrixing and mute control) is maintained during Standby mode
Before switching to Standby mode, the output SCART mute is recommended if the demodulated
sound source (DSP_OSCART) is selected by this output. This source might cause an audible plop
during the digital power down.
