Subject: [PATCH] ALSA: hda/realtek: Fix internal mic on Minisforum V3 and V3
 SE

On the Minisforum V3 and V3 SE (ALC245, PCI SSID 1f4c:e001) the
internal digital microphone array never produces any audio. The DMIC
pin 0x12 is parsed correctly ("Internal Mic=0x12"), but the headset mic
jack pin 0x19 (BIOS pin config 0x04a19050, jack detect enabled) has no
presence detect wired on these boards: reading GET_PIN_SENSE on 0x19
always returns "present" (as it does on the unused, unconnected pin
0x18), while the headphone jack 0x21 reports correctly.

The generic parser therefore sets up auto-mic switching and, believing
an external mic is always plugged in, permanently routes the ADC to the
empty jack (mixer 0x23 input 0x19 unmuted, input 0x12 muted). The
"Mic Jack" kcontrol reports "on" with nothing plugged in.

Mark pin 0x19 as having no presence detect. The parser then stops
auto-switching and exposes a normal "Capture Source" (Internal Mic /
Mic) control, which desktop audio stacks drive from their Internal
Microphone / Microphone ports. The existing bass speaker DAC routing is
kept by chaining to ALC245_FIXUP_BASS_HP_DAC.

Tested on both models with the same pin config applied through a
snd-hda-intel patch firmware ([pincfg] 0x19 0x04a19150):
 - V3 SE (Ryzen 7 7735U, BIOS 1.03), kernel 7.2.6
 - V3 (Ryzen 7 8840U, BIOS 1.06), kernel 7.2.7
Both boards report the same codec SSID and the same 0x19 default. On
both, the internal mic records at a normal level, headphone jack
detection on 0x21 still switches output, and the bass routing is
retained (DAC1/DAC2 Playback Volume controls present). A headset mic
on the combo jack was not tested (none available); with this change it
has to be selected manually. V3 users already report that the jack mic
gets no input [1], which is the other symptom of the same broken
presence detect.

The patched alc269.c was build-tested with W=1 on tiwai/sound.git
for-linus (7.3-rc3) without new warnings.

The diagnosis, the fixup and this changelog were written with the help
of an AI coding assistant; I reviewed them and tested the change on the
hardware listed above.

[PATCH 7.3.y 1/2] ALSA: hda/realtek: Fix speakers on ASUS ExpertBook PM3606CHA

[Sasha Levin]

From: Saim Masood <s.m.saim074@gmail.com>

[ Upstream commit 556cca74b6ec6f0bc6a3dc27473487de3cc8c8fe ]

The internal speakers of the ASUS ExpertBook PM3606CHA (Realtek ALC256,
PCI SSID 1043:3501) stay silent with the default codec setup, and the
headphone jack is not detected either.  The codec needs COEF values that
differ from its power-on defaults: COEF 0x10, 0x16, 0x35, 0x37 and 0x57
on NID 0x20 have to be set to the values used by the Windows driver.
Toggling the codec GPIOs, and the existing ALC256 fixups alone, make no
difference.

Apply the COEFs from a new fixup at the INIT action, so that they are
restored after resume as well.  Chain to ALC256_FIXUP_ASUS_MIC_NO_PRESENCE
to keep the headset mic and the jack detection working, which the
fallback pin quirk provided before for this machine.

The COEF values were found by the reporter of the Ubuntu bug below, who
compared the codec state against the one under the Windows driver.

Tested on an ASUS ExpertBook PM3606CHA (BIOS PM3606CHA.304) with the
change applied to v7.2.5: with this fixup alone, the speakers, the
headphones with jack detection, and the headset mic all work, also
after suspend and resume.
