Hi ALSA ML I noticed samsung speyside driver has duplicate line on audio_paths. I think it is typo or something... linux/sound/soc/samsung/speyside.c static struct snd_soc_dapm_route audio_paths[] = { => { "IN1RN", NULL, "MICB1" }, { "IN1RP", NULL, "MICB1" }, { "IN1RN", NULL, "MICB2" }, { "IN1RP", NULL, "MICB2" }, { "MICB1", NULL, "Headset Mic", speyside_get_micbias }, { "MICB2", NULL, "Headset Mic", speyside_get_micbias }, { "IN1LP", NULL, "MICB2" }, => { "IN1RN", NULL, "MICB1" }, { "MICB2", NULL, "Main AMIC" }, ... Thank you for your help !! Best regards --- Kuninori Morimoto
