No, micbias2 and DMIC are independent and micbias2 will not be enabled if we don't add it in the audio route. So I don't think we need to disable it if dmic pin-mapping is specified. > > 2) Do headset mics normally need a bias current? Could this be headset > dependent? Yes, but we don't need to set specific register for that. It means you don't need to add "micbias1" in the audio route for headset mic. I think all headset mic will need a bias current. > > Regards, > > Hans > _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
