ALSA: hda/cs420x: Add CS4208 fixup for iMac16,1

2026-05-27T05:24:15+00:00

The 21.5" Retina 4K iMac (Late 2015, DMI product name "iMac16,1") ships with a Cirrus Logic CS4208 codec wired to an external speaker amplifier enabled through codec GPIO0 -- the same arrangement as the late-2013 MacBookPro 11,x. Without a matching entry in cs4208_mac_fixup_tbl[] the fixup picker logs: snd_hda_codec_cs420x hdaudioC1D0: CS4208: picked fixup for codec SSID 106b:0000 i.e. an empty fixup name, GPIO0 stays low, the external amp is never powered up, and the internal speakers are silent on a stock kernel. The codec SSID reported by hardware is 0x106b:0x7f00. Reusing CS4208_MBP11 (GPIO0 + SPDIF switch fixup) makes the internal speakers and S/PDIF output work out of the box, removing the need for users to set `options snd_hda_intel model=mbp11` via /etc/modprobe.d/. Tested on iMac16,1 (kernel 6.17.0): four internal drivers (Left tweeter, Left woofer, Right tweeter, Right woofer, exposed as the 4 channels of the analog-surround-40 ALSA profile) produce audio after the fixup is applied.

ALSA: hda/realtek: Limit mic boost on Positivo DN140

ALSA: hda: cs35l56: Fix system name string leaks

2026-05-25T07:22:23+00:00

cs35l56_hda_read_acpi() gets an allocated ACPI _SUB string from acpi_get_subsystem_id(). On success, that string is used to create the firmware system name. Several error paths after the _SUB lookup can return without releasing the allocated string. This includes speaker ID lookup errors other than -ENOENT, and errors after a firmware system name has been allocated. Use scoped cleanup for the temporary _SUB string and make cs35l56->system_name device-managed. This releases the temporary _SUB string on every error path and lets devres release the firmware system name on probe failure and device removal.

ALSA: hda/realtek: Add HDA_CODEC_QUIRK for Lenovo Yoga Slim 7 14AGP11

2026-05-25T07:21:11+00:00

The BIOS on the Lenovo Yoga Slim 7 14AGP11 (AMD Ryzen AI / Kraken Point chassis; board LNVNB161216, product 83QS) programs the PCI subsystem ID of the HDA function as 17aa:0000. As a result no entry in alc269_fixup_tbl[] matches via SND_PCI_QUIRK, the fixup falls back to the generic auto-routing path, and the bass speaker pin is left mis-routed. Laptop speakers sound noticeably thin. The codec's own internal subsystem ID register reports 0x17aa394c correctly, so an HDA_CODEC_QUIRK entry (which matches on the codec SSID rather than on the PCI SSID) binds the chassis to the existing ALC287_FIXUP_YOGA9_14IAP7_BASS_SPK_PIN fixup. This mirrors the same workaround already in place for the closely-related Yoga 7 2-in-1 14AKP10 and 16AKP10 entries earlier in the table. With this change the kernel log goes from ALC287: picked fixup for PCI SSID 17aa:0000 to ALC287: picked fixup alc287-yoga9-bass-spk-pin and speaker routing matches what the firmware intended. Verified by the reporter against the equivalent modprobe override (model=,alc287-yoga9-bass-spk-pin).

The comment for the pin configuration 0x21 in the fixup ALC299_FIXUP_PREDATOR_SPK states "use as headset mic, without its own jack detect", but the fixup name and the actual usage indicate that the pin is meant to be used as internal speaker.

ALSA: hda/intel: Make sure to cancel irq-pending work at closing PCM stream

2026-05-20T05:50:45+00:00

The pending irq work might be still floating while the assigned stream has been already closed, which may lead to UAF, especially when another async work for fasync is involved. For addressing this, extend the hda_controller_ops for allowing the extra cleanup procedure that is specific to the controller driver, and make sure to cancel and sync the pending irq work at each PCM close before releasing the resources.

ALSA: hda: Move irq pending work into hda-intel stream

2026-05-20T05:50:45+00:00

Currently, the delayed IRQ handling for PCM streams is managed in a single work embedded in hda_intel, but this is basically a per-stream thing. Due to the single work, we can't cancel the work properly at closing each stream, for example. For making the IRQ pending work to be stream-based, this patch changes the following: - An extended version of azx_dev (i.e. the hd-audio stream object) is defined for snd-hda-intel - The irq_pending flag and irq_pending_work are moved to hda_intel_stream, so that they can be hda-intel stream specific - The stream creation and assignment are refactored so that snd-hda-intel can handle individually; the snd-hda-intel specific workaround for stream tags is also moved to snd-hda-intel itself instead of the common code - The irq pending work is canceled properly at free / shutdown While we're at it, changed the bit field flag to bool, as the bit field doesn't help much in our case.
