92HD71B7 does not support automatic routing of the PC_Beep pin to all outputs when the link is in
reset. Analog PC-Beep may be supported during Link Reset if the mixer is present and manually
configured for pass-thru. Reset# must be high and Bit_Clk active. Analog PC_Beep is available as
an input to the analog mixer.
This product implements a +3dBV output option on headphone capable ports. (HP output and line
output levels are defined as 1Vrms with an option to enable +3dBV FSOV using a vendor specific
verb.)
1.4.16.1. GPIO Pin mapping and shared functions.
1.4.16.2. Volume/Digital Microphone/GPIO Selection
To determine which function is actually enabled on pins2 and 4, the order of precedence is followed:
1) If the GPIOs are enabled, they override both Volume Control and Digital Mics
2) If the GPIOs are not enabled through the AFG, then at reset, the Volume control is enabled with
the weak pull-up.
