Hi Chen-Yu, > My apologies. I didn't notice that VMIC was already in the driver. > In that your original patch did everything right. Don't worry about it :) But I have a question: If I replace DAPM_INPUT by DAPM_MIC it wants a callback that is supposed to fiddle with the bias. Do I provide one? If so, will it conflict with the supply? Or do I leave it as DAPM_INPUT ? _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
