If anyone has any objections, please let me know. ------------------ From: Jared Wuerzburger [ Upstream commit 72107104d4f522405c9dfdfbaeb230e371c295ee ] 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.
