PCV [3:0]
PC Beep Volume Control. The least significant bit represents 3 dB attenuation. This register controls the output
from 0 dB to a maximum attenuation of –45 dB. The PC Beep is routed to the Left and Right Line outputs even
when AD1819B is in a RESET State. This is so that Power-On Self Test (POST) codes can be heard by the user
in case of a hardware problem with the PC.
PC Beep Mute. When this bit is set to “1,” the channel is muted.
