The STAC9758 VIDEO_IN path to the mixer (including the volume control of Register 14h) is used
by DAC-B. The VIDEO_IN pins are redefined as the second microphone input. However, the Video
Input functionality can be implemented by the flexible input/output structure of the
STAC9758, called Universal Jacks. This technology allows for selectable input paths. The
STAC9758 has a Line In Mux that can select a variety of input options. Using the Line In Mux to

The channels to be affected are determined by the SPLITMUTE bit
(Reg 72, Page 0, D6).
If SPLITMUTE = 0, both Left and Right channels are muted
If SPLITMUTE = 1, only the Left Channel is muted

The SPLITMUTE bit (Reg 72, Page 0, D6) must be set to 1 in order for the
RMute bit to have an effect on the sound.
The RMute bit is R/W. The RMute bit may be written and read regardless
of the state of the SPLITMUTE bit.
