AC’97 2.3 CODECS WITH STEREO MICROPHONE & UNIVERSAL JACK
STAC9752A/9753A
AC’97 2.3 CODECS WITH STEREO MICROPHONE & UNIVERSAL JACK
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 the STAC9752A/9753A to the speakers, while most of the system in
low power mode. The procedure for this follows the previous example, except that the analog mixer
is never shut down.
