7 daysALSA: hda/realtek: Add mute LED quirk for HP Victus 16-e0xxx (MB 88ED)André Pragosa
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.

9 daysALSA: hda/realtek: Add quirk for Infinix INBOOK X3 SlimGunal Seenivasagan
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.

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.

2026-07-20ALSA: hda/tas2781: clear cali_data.total_sz when calibration read failsPhilipp Oster
tas2563_save_calibration() assigns cali_data.total_sz before it reads the per-device calibration data from EFI, but its error paths return without clearing it again. cali_data.cali_reg_array is left all zero, because the function returns before the register addresses are assigned. On the first playback tasdev_load_calibrated_data() does if (!data || !cali_data->total_sz) return; which passes, since total_sz is still non-zero. It then issues five 4-byte bulk writes to p->r0_reg, p->r0_low_reg, p->invr0_reg, p->pow_reg and p->tlimit_reg, all of which are 0. Register 0 decodes to book 0 / page 0 / register 0x00, so the auto-incrementing block write zeroes registers 0x00 to 0x03. Register 0x03 is PB_CFG1, which holds AMP_LEVEL, so the amplifier gain is set to its minimum and the speaker stays silent. This is reproducible on a Lenovo Yoga 7 14ARB7 (two TAS2563 on I2C, ACPI INT8866) whose factory calibration was never written to UEFI, so the EFI read fails with EFI_NOT_FOUND. The two woofers driven by the amplifiers are silent while the tweeters driven directly by the ALC287 play. Reading the amplifier registers over i2c shows PWR_CTL = 0x00 (active) and the TDM slots correctly programmed by the RCA profile, but PB_CFG1 = 0x00. With this change PB_CFG1 keeps its power-on default of 0x20 and both woofers play. tas2781_save_calibration() in tas2781_hda.c already clears total_sz on failure; do the same for the TAS2563 variant.

2026-07-18ALSA: hda/realtek: Add quirk for HP Pavilion x360Takashi Iwai
HP Pavilion x360 sets a bogus PCI SSID (103c:0000), hence the driver picks up a wrong quirk entry, resulting in an almost silent output. And yet, the existing quirk for x390 doesn't seem sufficing, and we need the extra setup for the amp. This patch adds the quirk entry for the codec SSID (103c:8486) to initialize the amp via COEF verbs and chains to the existing quirk for another x360 model to address the silent output.

2026-07-16ALSA: hda/realtek: Add inverted LED quirk for HP ZBook 8 G2aChris Chiu
HP ZBook 8 G2a 14 and 16 (SSIDs 0x103c:0x8f94, 0x103c:0x8f95) use the Realtek ALC245 codec with a TAS2781 amplifier via I2C. They share the same hardware configuration as the existing 0x8f40/0x8f41/0x8f42/0x8f62 models but have inverted speaker mute LED polarity, so the existing ALC245_FIXUP_HP_TAS2781_I2C_MUTE_LED quirk drives the LED backwards: off when muted and on when unmuted. Add a dedicated quirk with inverted COEF values. These are speaker-only models without an HP pin, so the LED is driven directly through the vmaster_mute hook; there is no need to probe the HP pin at runtime since the configuration is static and known per SSID.

2026-07-16ALSA: hda: codecs: hdmi: disable keep-alive before audio format changeKai Vehmanen
When a keep-alive (KAE) silent stream is active on an Intel HDMI/DP codec, opening a real PCM stream reprograms the converter format and the audio infoframe in snd_hda_hdmi_generic_pcm_prepare(). Part of that reprogramming - the converter channel count and the channel mapping in snd_hda_hdmi_setup_audio_infoframe() - is not safe to do while a keep-alive stream is active. This is most visible when switching to a multichannel PCM configuration, where the active channel count actually changes. In that case the newly opened PCM stream plays no sound. Add an optional hdmi_ops .prepare hook, called at the start of the PCM prepare sequence (before the format and infoframe are touched), and implement it for HSW+ to release keep-alive. Keep-alive is then re-enabled as before once the new stream has been set up, in the setup_stream op.

2026-07-15ALSA: hda: cs35l41: validate and free ACPI mute objectGuangshuo Li
cs35l41_get_acpi_mute_state() evaluates a _DSM method to get the ACPI mute state and reads the first byte from the returned object. However, the returned ACPI object is owned by the caller and is never freed after use, so each successful query leaks the _DSM result object. The code also assumes that the returned object is a buffer with at least one byte. A malformed firmware response can return a different object type or an empty buffer, and the direct ret->buffer.pointer dereference can then access an invalid pointer. Use the typed _DSM helper, validate that the returned buffer contains at least one byte, and free the ACPI object after reading it.

Since only 38a8 has a codec SSID quirk, these machines fall through to the PCI SSID match 17aa:386f (Legion Pro 7i 16IAX7) and get ALC287_FIXUP_CS35L41_I2C_2, which probes the Cirrus amplifiers of the Intel variant.

Make the Kconfig item for cirrus_scodec visible if CONFIG_KUNIT is enabled. This is so that its KUnit test can be enabled by KUnit scripts without requiring a large amount of irrelevant additional components. The general rule for KUNIT_ALL_TESTS is that it should only enable tests for components that are already selected. However, the UML environment does not support ACPI, which means the HDA codec drivers that use cirrus_scodec cannot be selected. But cirrus_scodec does not need ACPI. By making the Kconfig option visible if CONFIG_KUNIT, the KUnit test can be enabled with only the minimal set of functionality that is required for cirrus_scodec. This is still compliant with the KUNIT_ALL_TESTS rule "only tests for enabled modules" because by default cirrus_scodec will only be enabled if the drivers that use it are enabled. It must be intentionally enabled to force it to be included for testing.

That reads back the selected index instead of the coefficient value. hda_reg_write_coef() has the same issue and builds the value write from AC_VERB_GET_COEF_INDEX instead of AC_VERB_SET_PROC_COEF. This only affects the regmap coefficient cache path used by codecs that set codec->cache_coef. Direct coefficient helpers already use the normal SET_COEF_INDEX followed by GET_PROC_COEF or SET_PROC_COEF sequence, which is likely why this has not been noticed widely. Use AC_VERB_GET_PROC_COEF for cached coefficient reads and AC_VERB_SET_PROC_COEF for cached coefficient writes.

2026-07-07ALSA: hda/realtek: Fix headset mic on ASUS ROG Ally XMatthew Schwartz
The ASUS ROG Ally X (RC72LA, PCI SSID 0x1043:0x1eb3) leaves the combo jack microphone pin (0x19) unconfigured, so a headset microphone is neither detected nor captured. Only the internal microphone is available. Add a pin override that configures node 0x19 as an external headset mic, the same way the original ROG Ally does. The headphone output fixup chain is preserved, so speaker and headphone routing are unchanged.

2026-07-07ALSA: hda/realtek: Fix headphone output on ASUS ROG Ally XMatthew Schwartz
The ASUS ROG Ally X (RC72LA, PCI SSID 0x1043:0x1eb3) with an ALC294 codec produces no sound from the headphone jack, and unplugging the headphones can leave the speakers muted too. The device uses ALC287_FIXUP_TAS2781_I2C, which chains into the ThinkPad fixup chain. alc285_fixup_thinkpad_x1_gen7() makes the headphone (pin 0x21) and speaker (pin 0x17) share DAC 0x03. That is correct for a ThinkPad, but here the shared DAC is exposed as a "Line Out" control that defaults to zero, so the headphones stay silent when plugged in. Add a dedicated fixup chain for the Ally X that sets up the TAS2781 amplifier and the headset jack without the ThinkPad DAC sharing, and routes the speaker to DAC 0x02 so the headphone and speaker get independent DACs. Also, fixup the wrong product code (it's RC72LA, not RCLA72).

Lenovo Legion 7i 16IAX7 systems with Realtek ALC287 codec SSID 17aa:3874 and CSC3551/CS35L41 speaker amps do not provide the required CS35L41 _DSD properties in ACPI.

Without a matching quirk the LEDs are never registered, so the front-panel mic-mute LED stays permanently lit and does not track the mute state. Apply ALC285_FIXUP_HP_GPIO_LED, mirroring the sibling EliteBook entries. With this fixup the codec registers an "hda::micmute" LED class device and the LED correctly follows the capture-mute state.

gitolite.kernel.org:pub/scm/linux/kernel/git/tip/tip Pull timekeeping updates from Thomas Gleixner: "Updates for NTP/timekeeping and PTP: - Expand timekeeping snapshot mechanisms The various snapshot functions are mostly used for PTP to collect "atomic" snapshots of various involved clocks. They lack support for the recently introduced AUX clocks and do not provide the underlying counter value (e.g. TSC) to user space. Exposing the counter value snapshot allows for better control and steering. Convert the hard wired ktime_get_snapshot() to take a clock ID, which allows the caller to select the clock ID to be captured along with CLOCK_MONONOTONIC_RAW. Additionally capture the underlying hardware counter value and the clock source ID of the counter. Expand the hardware based snapshot capture where devices provide a mechanism to snapshot the hardware PTP clock and the system counter (usually via PCI/PTM) to support AUX clocks and also provide the captured counter value back to the caller and not only the clock timestamps derived from it. - Add a new optional read_snapshot() callback to clocksources That is required to capture atomic snapshots from clocksources which are derived from TSC with a scaling mechanism (e.g. Hyper-V, KVMclock). The value pair is handed back in the snapshot structure to the callers, so they can do the necessary correlations in a more precise way. This touches usage sites of the affected functions and data structure all over the tree, but stays fully backwards compatible for the existing user space exposed interfaces.
