ALSA: usb-audio: Add delay quirk for iBasso DC-Elite

2026-07-13T15:06:20+00:00

Audio control requests that sets sampling frequency sometimes fail on
this card. Adding delay between control messages eliminates that problem.

ALSA: hda: conexant: Remove mic bias threshold override

2026-07-13T15:04:33+00:00

Remove the mic bias current comparator threshold override (NID 0x1c,
verb 0x320, value 0x010) from Conexant codec driver.

This override was originally intended to support volume up/down controls on
headsets with inline remote controls, but it causes microphone detection
failures on some headsets with impedance less than 1k ohm.

After consulting with the vendor's engineers, it was confirmed that this
setting is board-specific and should be handled by BIOS/firmware rather
than the generic codec driver, especially since inline remote support
is not currently implemented.

ALSA: hda/realtek: Fix speakers on Legion Pro 7 16ARX8H with codec SSID 17aa:38a7

2026-07-13T10:04:59+00:00

Some units of the Lenovo Legion Pro 7 16ARX8H (82WS) report codec
subsystem ID 17aa:38a7 instead of 17aa:38a8. 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. The TI
TAS2781 amplifier (ACPI TIAS2781:00) present on this AMD variant is
never bound and the internal speakers remain silent.

Add a codec SSID quirk for 17aa:38a7 pointing to
ALC287_FIXUP_TAS2781_I2C, mirroring the existing 38a8 entry.

Tested on a Legion Pro 7 16ARX8H (82WS, BIOS LPCN62WW): with the codec
SSID overridden to 17aa:38a8 via the HDA patch loader, the TAS2781
amplifier binds and the internal speakers work.

ALSA: hda/realtek: Fix speakers on MECHREVO WUJIE Series

2026-07-13T10:04:25+00:00

The internal speakers on the MECHREVO WUJIE Series are silent,
while the headphone output works correctly.

The BIOS reports NID 0x1b on the Realtek ALC233 codec as
unconnected with pin configuration 0x411111f0. However, the pin
is connected to an internal speaker.

Overriding NID 0x1b with 0x90170150 makes the HDA generic parser
detect both 0x14 and 0x1b as speaker outputs and restores internal
speaker playback.

Add a pin configuration fixup for the affected PCI SSID c011:1d05.

Tested on a MECHREVO WUJIE Series laptop with board
WUJIE Series-Lark4-LNL and firmware EM_LNL326_V1.0.23.

ALSA: hda: cs35l56: Fail if wmfw file is missing

2026-07-13T10:03:48+00:00

Fail cs35l56_hda_fw_load() and log an error if it didn't find a wmfw file
and the BIOS didn't patch the firmware already. Also remove a section of
code from cs35l56_hda_request_firmware_files() that attempted to find a
.bin if a .wmfw was not found.

The CS35L56 ROM can only provide default audio in SoundWire mode. A wmfw
is needed to enable I2S audio. Also none of the customer-specific .bin
files are compatible with the ROM firmware. So a .wmfw file is always
required.

ALSA: usb-audio: Skip DSD quirk for Musical Fidelity M6s DAC

2026-07-13T10:02:51+00:00

Salvador reported that the recent fix for applying the DSD quirk to
Musical Fidelity devices broke for his M6s DAC model (2772:0502).

Although this is basically a firmware bug, the model in question is
fairly old, and no further firmware update can be expected, so it'd be
better to address in the driver side.

As an ad hoc workaround, skip the DSD quirk for this device by adding
an empty quirk entry of 2772:0502; this essentially skips the later
DSD quirk entry by the match with the vendor 2772.

ALSA: hda/cirrus_scodec: Make Kconfig visible if KUNIT

2026-07-09T16:34:21+00:00

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.

ALSA: hda/realtek - Fixed Headphone noise issue for Dell QCM1255

2026-07-09T09:12:59+00:00

This platform booted with Ubuntu 24.04 with Pipewire audio server. So,
it has pop noise with headphone. But it's normal with Pulseaudio server.
This patch was the workaround. Connect the headphones to DAC 0x2.
The popping sound will disappear.
