TWO-CHANNEL, 20-BIT, AC’97 2.3 CODECS WITH HEADPHONE DRIVE, SPDIF OUTPUT MICROPHONE & JACK SENSING
Figure 23 illustrates a state when all the mixers should work with the static volume settings that are
contained in their associated registers. This configuration can be used when playing a CD (or exter-
nal LINE_IN source) through STAC9752/9753 to the speakers, while most of the system in low
power mode. The procedure for this follows the previous except that the analog mixer is never shut
down.
