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 Left and Right Line outputs even when
the
RESET
pin is asserted. 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.
