The Digital Volume Control registers allow independent control of the signal levels in 1 dB increments
from 0 to -119 dB. Volume settings are decoded as shown in Table 3. The volume changes are im-
plemented as dictated by the Soft Ramp and Zero Cross bits. All volume settings less than -119 dB
are equivalent to enabling the MUTE bit.

When Immediate Change is selected all level changes will be implemented immediately in one step.
Zero Cross Enable dictates that signal level changes, either by attenuation changes or muting, will
occur on a signal zero crossing to minimize audible artifacts. The requested level change will occur
after a timeout period between 512 and 1024 sample periods (10.7 ms to 21.3 ms at 48 kHz sample
rate) if the signal does not encounter a zero crossing. The zero cross function is independently mon-
itored and implemented for each channel.
Soft Ramp allows level changes, both muting and attenuation, to be implemented by incrementally
ramping, in 1/8 dB steps, from the current level to the new level at a rate of 1 dB per 8 left/right clock
periods.
Soft Ramp and Zero Cross dictates that signal level changes, either by attenuation changes or mut-
ing, will occur in 1/8 dB steps and will be implemented on successive signal zero crossings. The 1/8
dB level changes will occur after timeout periods between 512 and 1024 sample periods (10.7 ms to
21.3 ms at 48 kHz sample rate) if the signal does not encounter zero crossings. The zero cross func-
tion is independently monitored and implemented for each channel.
