Thanks Stefan. Assuming the previous patches were not applied, here is the complete and correct patch that has now been applied upstream:


On the System76 Gazelle (gaze14) variants with a GTX 1660Ti, there is a headset
microphone input attached to 0x1a that does not have a jack detect. In order to
get it working, the pin configuration needs to be set correctly, and the
ALC269_FIXUP_HEADSET_MODE_NO_HP_MIC fixup needs to be applied. This is
identical to the ALC293_FIXUP_SYSTEM76_MIC_NO_PRESENCE fixup already applied
for the System76 Darter Pro (darp5).

On the System76 Gazelle (gaze14) variants with a GTX 1650, there is a headset
microphone input that is not parsed correctly. In order to get it working, the  
ALC269_FIXUP_HEADSET_MIC fixup needs to be applied.

Tests were done on all four variants ensuring full audio capability:
- 15 inch with GTX 1660 Ti (0x8550)
- 17 inch with GTX 1660 Ti (0x8551)
- 15 inch with GTX 1650 (0x8560)
- 17 inch with GTX 1650 (0x8561)
