Independent Mode
This is enabled by setting the BAL_MODE bits in both the
registers to Independent mode. In this case, the register values are used to control the volume/
balance functions as described in
Mute Control
An Independent Mute Control can be used to smooth audio envelope variations in order to prevent
any audible plops can be applied to all audio outputs. This feature is controlled by register
ANA_LS_HP.
A Headphone Detection Mode that will automatically mute the Loudspeaker and Subwoofer outputs
when a headphone is detected can be enabled by the HDP_ON bit in the
this case, only the Headphone output will remain active. See also
and
When a demodulated source is selected on the audio output, the mute is also controlled by
Automatic Standard Recognition system (AUTOSTD). In case of no mono detected or bad detection
of language without backup, the corresponding audio output is automatically muted. In case of
multi-language, the output will be de-muted by selecting an other language with backup.
