[alsa-devel] [PATCH] ALSA: hda - Add Dell headset detection quirk for one more laptop model

[Hui Wang]

On the Dell machines with codec whose Subsystem Id is 0x10280640,
no external microphone can be detected when plugging a 3-ring headset.
If we add "model=dell-headset-multi" for the snd-hda-intel.ko, the
problem will disappear.

The codec (Vendor ID: 0x10ec0255) on the machine belongs to alc_269
family.
