ALSA: hdspm: Add a new PCI device ID (1d18:3fc6) for RME HDSPe AIO PCI express audio

2026-09-10T15:51:32+00:00

The RME HDSPe AIO PCI express audio card has a new PCI vendor ID (1d18) while keeping the same device ID (3fc6). The card seems working fine by just adding the new ID. While we're at it, use the standard macro to cleann up the existing PCI ID entry, too.

Merge tag 'asoc-fix-v7.3-rc2' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus

2026-09-09T13:09:55+00:00

ASoC: Fixes for v7.3 An unusually large batch of fixes here, partly due to me not sending a pull request last week and partly due to Linus' fixes for the Ericsson systems. I'm fairly sure he's the only user there so it seemed low risk to handle as fixes. We also have a batch of error handling fixes from Cezary and issues with uninitialised stream_config->type from Shuming both of which had user error reports attached. Otherwise everything is a fairly normal combination of quirks and device specific fixes.

ASoC: amd: acp-da7219-max98357a: don't bind on Raven/Picasso boards

2026-09-08T14:59:06+00:00

The "AMDI5682" ACPI HID is matched by two AMD ASoC machine drivers: cz-da7219-max98357a (this driver, Carrizo/Stoney) and acp3x-alc5682-max98357 (Raven/Picasso). cz-da7219-max98357a is linked first and probes the platform device first; its DAI links reference the Stoney ACP, which is absent on Raven/Picasso, so its card can never be instantiated there. This was harmless until commit 42d99857d6f0 ("ASoC: core: Move all users to deferrable card binding"): devm_snd_soc_register_card() now returns 0 for a card left pending instead of propagating -EPROBE_DEFER, so cz_probe() succeeds and permanently binds AMDI5682. acp3x-alc5682-max98357 never binds and the internal speakers and headphone jack get no card. Detect Raven/Picasso (and later) by the ACP3.x audio coprocessor's dedicated PCI function (1022:15e2); Carrizo/Stoney reach the ACP through the GPU driver and have no such device. Return -ENODEV so the driver core continues probing AMDI5682 with acp3x-alc5682-max98357.

ALSA: hda: Report a change when only the channel status bytes move

2026-09-08T14:23:16+00:00

The put() callback of "IEC958 Playback Default" returns whether the converted register value moved. The convert_from_spdif_status() helper reads part of the first two channel status bytes and none of the last two, while the get() callback returns all four. So a write that lands only in the bits it does not read changes what userspace reads back and reports no change. Of the 31 bits above the mode bit, 20 are such bits in consumer mode and 29 in professional mode. The core notifies only on a positive return. Toggling status[2] bit 0 on an HDA HDMI codec moves the read-back from 04 00 00 00 to 04 00 01 00 with no event. Toggling the non-audio bit in status[0] gives one. Compare the stored status as well, the way the ac97 code does. The write to the codec stays gated on the converted value.

ALSA: us122l: Prevent write upgrades for read mappings

2026-09-08T14:22:50+00:00

The hwdep mmap callback rejects read-buffer mappings that are initially writable, but leaves VM_MAYWRITE set on mappings created with PROT_READ. A process that can open the hwdep node O_RDWR can later use mprotect() to make the mapping writable. The read allocation begins with struct usb_stream. Its read_size member is used by the fault handler to decide which pages belong to the read buffer. The read VMA intentionally remains expandable because pcm_usb_stream uses mremap() after reading that size. Changing read_size first can therefore map and access pages beyond the allocation. The same member is also consumed by usb_stream_free(), where changing it can make free_pages_exact() release pages outside the allocation. Clear VM_MAYWRITE for read-buffer mappings after rejecting an initially writable VMA. This keeps the separate output-buffer mapping writable while preventing later permission upgrades.

ALSA: hda/realtek: Add quirk for HP Elite Dragonfly Max G2 speaker

2026-09-08T07:12:49+00:00

The HP Elite Dragonfly Max G2 Notebook PC (SSID 103c:8890) uses an ALC285 codec but is missing from the existing HP quirk table, unlike the related "HP Elite Dragonfly G2" entry (SSID 103c:8716). Without the quirk the right speaker amplifier's GPIO is never initialized, leaving it silent while the left speaker plays normally. Apply the existing ALC285_FIXUP_HP_GPIO_AMP_INIT fixup used by the 103c:8716 entry, which resolves the issue. Verified with speaker-test on both channels and confirmed correct routing to both the downward- firing woofer and upward-firing tweeter on each side via the board's passive crossover.

ASoC: cs35l56: Fix race between kexec and snd_soc_register_component()

2026-09-07T23:11:41+00:00

Use a reboot notifier and a mutex to prevent snd_soc_register_component() from racing with a kexec reboot. This prevents snd_soc_register_component() from manipulating device lists while device_shutdown() is walking them. Commit 1d80a4792f1de ("ASoC: cs35l56: Fix probe deadlock waiting for SoundWire enumeration") moved snd_soc_register_component() out of probe() into a workqueue item. See the description in that commit for a detailed explanation. That change introduces a race between snd_soc_register_component() and kexec. The reboot notifier and mutex prevent the shutdown race. There is one remaining race with KEXEC_JUMP because it does not invoke reboot notifiers or freeze freezable workqueues. But KEXEC_JUMP is rarely used and is supported on only two architectures (x86 and SuperH). It does not appear to be enabled by default in any distro. It is also unlikely there will be a KEXEC_JUMP before snd_soc_register_component() has had the opportunity to execute. Fixing this can be deferred to a future patch.

ASoC: amd: yc: add quirk for Acer Nitro AN17-41 internal mic

2026-09-07T21:00:25+00:00

The Acer Nitro AN17-41 uses "RB" as its board vendor and has no entry in yc_acp_quirk_table, so acp6x_probe() finds no DMI match, registers no card, and the internal digital microphone records only silence. Add a quirk entry for it so the DMIC is enabled. Signed-off-by: Aaron Welwood Link: https://patch.msgid.link/20260907031738.17257-1-abwelwood@gmail.com Signed-off-by: Mark Brown

ASoC: mt6351: Publish the OF module alias

2026-09-07T18:53:01+00:00

The MT6351 codec platform driver uses mt6351_of_match to bind devices with compatible mediatek,mt6351-sound. The codec can be a separate module, but the OF table is not exported to module alias metadata. Publish the existing table without changing codec matching, register access or the machine-driver configuration.
