Currently Micbias gets enabled only when the recording starts. We have a requirement where micbias need to be enabled all the time.
Is there a way to do this using DAPM?
I would like to know if below listed requirements are possible and how and in which driver(codec/machine) to implement it.
1) Enabling and disabling mic bias using a new amixer control.
2) Add micbias enable/disable functionality to the mic bias mode selection amixer control(Normal operation/High performance). I mean something similar 'Capture' control where we have a single amixer control for turning on capture and also to change capture volume.
Thanks and regards
