The path Headset Mic --> MICBIAS is wrong because connects a non-supply widget as a source with a supply widget as a sink. It's the other way around:
MICBIAS (source) --> Headset Mic (sink). This patch also shut up the following error message: rockchip-snd-max98090 sound: Connecting non-supply widget to supply widget is not supported (Headset Mic -> MICBIAS) rockchip-snd-max98090 sound: ASoC: no dapm match for Headset Mic --> (null) --> MICBIAS rockchip-snd-max98090 sound: ASoC: Failed to add route Headset Mic -> direct -> MICBIAS Signed-off-by: Enric Balletbo i Serra <[email protected]> --- Changes since v1: - Improve log message. sound/soc/rockchip/rockchip_max98090.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/sound/soc/rockchip/rockchip_max98090.c b/sound/soc/rockchip/rockchip_max98090.c index abb64a5..3da7891 100644 --- a/sound/soc/rockchip/rockchip_max98090.c +++ b/sound/soc/rockchip/rockchip_max98090.c @@ -53,7 +53,7 @@ static const struct snd_soc_dapm_widget rk_dapm_widgets[] = { static const struct snd_soc_dapm_route rk_audio_map[] = { {"IN34", NULL, "Headset Mic"}, {"IN34", NULL, "MICBIAS"}, - {"MICBIAS", NULL, "Headset Mic"}, + {"Headset Mic", NULL, "MICBIAS"}, {"DMICL", NULL, "Int Mic"}, {"Headphone", NULL, "HPL"}, {"Headphone", NULL, "HPR"}, -- 2.1.0
