ALSA: hda/tas2781: fix ACPI reference handling

2026-08-03T06:56:42+00:00

tas2781_read_acpi() gets a reference to the matching ACPI device and then looks up its first physical device node. After taking a reference to the physical device, it immediately drops the ACPI device reference. However, every later failure jumps to an error path that drops the ACPI device reference a second time. This unbalances the reference count and may prematurely release the ACPI device. In addition, acpi_get_first_physical_node() may return NULL. Without a check, the driver passes the NULL physical device to the property helper calls and may dereference it. Return -ENODEV when no physical device is associated with the ACPI node, and remove the duplicate acpi_dev_put() from the common error path.

ALSA: hda/realtek: Add mute LED quirk for HP Victus 16-e0xxx (MB 88ED)

2026-07-29T06:32:12+00:00

Add subsystem ID 103c:88ed to the existing HP Victus 16-e0xxx mute LED quirk list. The HP Victus 16-e0xxx with subsystem ID 103c:88ed uses the same mute LED coefficient configuration as the already supported 103c:88eb variant. The mute LED was verified by manually toggling coefficient index 0x0b (bit 3) using hda-verb. After adding the quirk, the LED is registered as hda::mute and follows the audio mute state.

ALSA: hda/realtek: Add quirk for HP Dragonfly Folio G3 2-in-1 (103c:8a05)

2026-07-27T13:54:17+00:00

The HP Dragonfly Folio G3 2-in-1 also ships with PCI SSID 103c:8a05. On this unit the ALC245 codec reports subsystem id 103c:8a06 - the SSID that is already covered by commit 0a10faad5ca5 ("ALSA: hda/realtek: add quirk for HP Dragonfly Folio G3 2-in-1") - while the PCI SSID that SND_PCI_QUIRK matches against is 103c:8a05: snd_hda_codec_alc269 ehdaudio0D0: ALC245: picked fixup for PCI SSID 103c:8a05 cs35l41-hda spi1-CSC3551:00-cs35l41-hda.0: CS35L41 Bound - SSID: 103C8A06 The existing entry therefore never applies here, the four CS35L41 amplifiers on SPI are not registered and the internal speakers stay silent. Add the same fixup that the 8a06 entry uses: the four amplifiers bind and the speaker mute LED (codec GPIO 0x04) works.

ALSA:hda/realtek:ALC269 fixup for Legion 7 15ASH11 Mic Mute LED

2026-07-27T13:53:21+00:00

Lenovo Legion 7 15ASH11 with AMD RYZEN AI MAX+ 392 (Strix Halo, ACP 7.0) uses Realtek ALC287 series codec. Its audio subsystem adopts a hardware design similar to that of the Yoga Pro 7 15ASH11. It shares PCI SSID 17aa:38f9 with Thinkbook 16P Gen5. Therefore, use HDA_CODEC_QUIRK to apply ALC287_FIXUP_LENOVO_YOGA_PRO7 for identification. After added the HDA_CODEC_QUIRK quirk special for Lenovo Legion 7 15ASH11, the mic mute LED works well.

ALSA: hda/realtek: Add quirk for Infinix INBOOK X3 Slim

2026-07-26T13:55:52+00:00

The Infinix INBOOK X3 Slim (ALC269VB, subsystem 0x2782:0250) has its internal speakers wired to pin 0x1b, but the BIOS pin configuration table declares 0x1b as "no physical connection" (0x411111f0). It instead declares pin 0x14 as the internal speaker, although nothing is connected to 0x14. As a result the internal speakers are silent under Linux while the headphone jack works correctly. The codec output path to 0x14 is fully open (DAC assigned and streaming, mixer and pin unmuted, EAPD asserted), so the failure is silent with no error reported. The speakers work under Windows, where the vendor driver supplies its own pin table. Add a fixup that disables the unconnected pin 0x14 and declares pin 0x1b as the internal speaker. Reusing the existing ALC269VC_FIXUP_INFINIX_Y4_MAX was tried first, since it also remaps 0x1b to an internal speaker. It is not sufficient here: it leaves 0x14 declared, so autoconfig finds two line_outs line_outs=2 (0x14/0x1b/0x0/0x0/0x0) type:speaker and binds the primary "Speaker" control to the unconnected pin 0x14 while demoting the working speaker at 0x1b to "Bass Speaker". Audio is audible that way, but the volume and mute controls a desktop actually uses end up attached to a pin that is not wired to anything. Disabling 0x14 is what produces a single correct Speaker output. Verified on the affected machine: with the corrected pin configuration the driver's autoconfig reports line_outs=1 (0x1b/0x0/0x0/0x0/0x0) type:speaker both channels play, headphone auto-mute switches correctly in both directions, and audio survives codec runtime suspend (D3) and resume.

ALSA: hda/realtek: Fix headset mic on Acer Nitro 5 AN515-46

2026-07-26T06:57:48+00:00

The Acer Nitro 5 AN515-46 (SSID 1025:159e, Realtek ALC287) has a combo headset jack whose microphone does not work out of the box: the BIOS leaves pin 0x19 unconfigured, so no headset mic is created. Apply ALC2XX_FIXUP_HEADSET_MIC, the same fixup already used by the sibling models AN515-57 (1025:1539) and AN517-55 (1025:1597), which makes the headset microphone work correctly. Tested on an Acer Nitro 5 AN515-46 by overriding the model via a patch firmware with model=alc2xx-fixup-headset-mic.

ALSA: hda/realtek: Add quirk for HP Pavilion All-in-One 27-ca1xxx

2026-07-22T11:28:49+00:00

This HP All-in-One desktop (model 27-ca1xxx) uses an ALC274 codec and has no sound from either the internal speakers or the headphone jack. The audio output requires a combination of a specific verb setup and GPIO configuration to become functional. Additionally, the power_save feature must be disabled; otherwise, audible clicks or pops occur during power state transitions.
