[PATCH v2 1/2] ALSA: hda/realtek: Fix headset mic on Legion AW88399 laptops

[Aaron Ma]

The ALC287 codec on Lenovo Legion AW88399 laptops does not mark
the combo-jack microphone as a headset mic, so the HDA parser
treats it as a plain microphone. The headset microphone route
and inline headset buttons are therefore unavailable.

Enable Realtek headset mode without treating the jack as a
headphone microphone, and enable headset jack button handling.
Suppress automatic microphone selection so the internal microphone
remains selectable while a headset is connected.

The existing 0x1d override is redundant: firmware already marks
that pin unused, and the override triggers a "SKU not ready
0x411111f0" warning. Drop it.

Changes in v2:
- Based on the original 1/3 (df2538d54b3c0 "Use AW88399 I2C fixup
  chain on Legion machines"): reworked to enable headset-mic mode
  and inline buttons.

[PATCH v2 2/2] ALSA: hda/realtek: Limit Legion AW88399 playback to stereo

[Aaron Ma]

The Legion AW88399 speaker routing sends a stereo FL/FR stream
to both speaker pairs. A four-channel stream leaves the front
pair silent, so advertising four channels exposes an unusable
playback mode.

Limit the analogue PCM and the multi-output runtime constraint
to two channels for the affected Legion codec SSIDs. This
exposes the usable stereo configuration and rejects
four-channel playback.

Changes in v2:
- Based on the original 2/3 (39adb275a45cd "Use quad channel map for
  Legion AW88399 speakers"), reworked: instead of advertising a quad
  channel map, playback is now limited to stereo because both speaker
  pairs carry the same stereo signal.

Hi Aaron,

Thank you for this, both patches look good to me. You addressed all
my previous points and I have no further objections (in fact, I think
these are clever and useful solutions).

Tested on Legion Pro 7 16AFR10H (SSID 17aa:3938): headset buttons work,
internal mic remains selectable with headset plugged in, SKU warning gone,
and no bogus 4.0 profiles exposed anymore.

For both patches:

Best regards,
Marco

Applied both patches to for-next branch now.
