92HD99
SINGLE CHIP PC AUDIO SYSTEM, CODEC+SPEAKER AMPLIFIER+CAPLESS HP+LDO
2.25. Microphone Mute Input
Available on silicon revision WB and beyond.
The 92HD99 supports a microphone mute input. An external switch or other circuit may directly
mute the CODEC without relying on software control. This is a most helpful feature for allowing the
end user to conveniently enforce privacy since it bypasses the record gain/mute functions typically
controlled by software. While recording is muted, any active stream will receive digital silence.
