PC Beep Register (Index 0Ah)
The following table shows the relationship between bits and the attenuation value. The attenuation step is 3dB with
a range of 0 to –45dB. PC_BEEP of the AK4544A is 0dB at default state.
The PC Beep is routed to L & R Line outputs directly when AK4544A is in a RESET State(Reset# is “L”) or when the mixer is
powerdown with Vref on(PR2=”1” and PR3=”0”). The PC BEEP isn’t routed to True Line Level Out under these states. 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. After Reset# goes “H”,
direct PC beep pass through becomes OFF.
