8 powered up and causes a popping noise on the speakers).
23 shutdown and follows some basic rules:-
26    Startup Order :- DAC --> Mixers --> Output PGA --> Digital Unmute
28    Shutdown Order :- Digital Mute --> Output PGA --> Mixers --> DAC
31 a PGA (programmable gain amplifier) before being output to the speakers.
37 Capture artifacts are somewhat easier to get rid as we can delay activating the
38 ADC until all the pops have occurred. This follows similar power rules to
43    Startup Order - Input PGA --> Mixers --> ADC
45    Shutdown Order - ADC --> Mixers --> Input PGA
48 Zipper Noise
50 An unwanted zipper noise can occur within the audio playback or capture stream
51 when a volume control is changed near its maximum gain value. The zipper noise
52 is heard when the gain increase or decrease changes the mean audio signal
54 for each volume control. The ZC forces the gain change to occur when the signal
