Why would this be varied at runtime rather than being something fixed when the system is designed?

Similarly here.
- SOC_SINGLE("ADC Mic Bias Switch", LINEIN_CFG, MICBIAS_EN, 1, 0),
- SOC_ENUM("ADC Mic Bias Level", a1_adc_mic_bias_level),
Why would micbias be user controlled rather than a DAPM widget as normal?
