[alsa-devel] [PATCH] ALSA: hda/realtek: Add headset mic support for Intel NUC Skull Canyon
by Kai-Heng Feng 20 Nov '17

20 Nov '17

Users have been using knob "model=dell-headset-multi" on Intel Skull Canyon for a while. Add the equivalent quirk, ALC269_FIXUP_DELL1_MIC_NO_PRESENCE for Skull Canyon.
