WM9713L
Register 20h controls the bass and treble response of the left and right audio DAC (but not AUXDAC).
Register 22h controls the microphone input configuration and microphone bias and detect configuration.
Register 24h controls the output volume mapping on headphone jack insertion.
Register 26h is for power management according to the AC’97 specification. Note that the actual state of many circuit
blocks depends on both register 26h AND registers 3Ch and 3Eh.
