ALSA: hda: cs35l56: Fix uninitialized value in cs35l56_hda_read_acpi()

2026-05-23T11:04:56+00:00

[ Upstream commit 90df4957a3271adf391b3432cd76a40887cf3273 ] Eliminate the uninitialized 'nval' in cs35l56_hda_read_acpi() if a system-specific quirk overrides processing of the dev-index property. The value is now stored in a new 'num_amps' member of struct cs35l56_hda so that the quirk handler can set the value. The quirk for the Lenovo Yoga Book 9i GenX replaces the values from the dev-index property with hardcoded indexes. So cs35l56_hda_read_acpi() would then skip reading the property. But this left the 'nval' local variable uninitialized when it is later passed to cirrus_scodec_get_speaker_id().

ALSA: hda/conexant: Fix missing error check for jack detection

2026-05-23T11:04:56+00:00

[ Upstream commit b0e2333a231107adedd38c6fcfe1adc6162716fc ] In cx_probe(), the return value of snd_hda_jack_detect_enable_callback() is ignored. This function returns a pointer, and if it fails (e.g., due to memory allocation failure), it returns an error pointer which must be checked using IS_ERR(). If the registration fails, the driver continues to probe, but the jack detection callback will not be registered. This can lead to a kernel crash later when the driver attempts to handle jack events or accesses the uninitialized structure. Check the return value using IS_ERR() and propagate the error via PTR_ERR() to the probe caller.

ALSA: hda: cs35l56: Propagate ASP TX source control errors

2026-05-17T15:14:33+00:00

[ Upstream commit 0faacc0841d66f3cf51989c10a83f3a82d52ff2c ] cs35l56_hda_mixer_get() ignores regmap_read() and cs35l56_hda_mixer_put() ignores regmap_update_bits_check(). This makes the ASP TX source controls report success when a regmap access fails. The write path returns no change instead of an error, and the read path continues after a failed read instead of aborting the control callback. Propagate the regmap errors, matching the posture and volume controls in this driver.

ALSA: ctxfi: Add fallback to default RSR for S/PDIF

2026-05-07T04:09:29+00:00

commit 7d61662197ecdc458e33e475b6ada7f6da61d364 upstream. spdif_passthru_playback_get_resources() uses atc->pll_rate as the RSR for the MSR calculation loop. However, pll_rate is only updated in atc_pll_init() and not in hw_pll_init(), so it remains 0 after the card init. When spdif_passthru_playback_setup() skips atc_pll_init() for 32000 Hz, (rsr * desc.msr) always becomes 0, causing the loop to spin indefinitely. Add fallback to use atc->rsr when atc->pll_rate is 0. This reflects the hardware state, since hw_card_init() already configures the PLL to the default RSR.

ALSA: ctxfi: Limit PTP to a single page

2026-04-22T11:18:59+00:00

commit e9418da50d9e5c496c22fe392e4ad74c038a94eb upstream. Commit 391e69143d0a increased CT_PTP_NUM from 1 to 4 to support 256 playback streams, but the additional pages are not used by the card correctly. The CT20K2 hardware already has multiple VMEM_PTPAL registers, but using them separately would require refactoring the entire virtual memory allocation logic. ct_vm_map() always uses PTEs in vm->ptp[0].area regardless of CT_PTP_NUM. On AMD64 systems, a single PTP covers 512 PTEs (2M). When aggregate memory allocations exceed this limit, ct_vm_map() tries to access beyond the allocated space and causes a page fault: BUG: unable to handle page fault for address: ffffd4ae8a10a000 Oops: Oops: 0002 [#1] SMP PTI RIP: 0010:ct_vm_map+0x17c/0x280 [snd_ctxfi] Call Trace: atc_pcm_playback_prepare+0x225/0x3b0 ct_pcm_playback_prepare+0x38/0x60 snd_pcm_do_prepare+0x2f/0x50 snd_pcm_action_single+0x36/0x90 snd_pcm_action_nonatomic+0xbf/0xd0 snd_pcm_ioctl+0x28/0x40 __x64_sys_ioctl+0x97/0xe0 do_syscall_64+0x81/0x610 entry_SYSCALL_64_after_hwframe+0x76/0x7e Revert CT_PTP_NUM to 1.

ALSA: hda/realtek: Add quirk for Lenovo Yoga Pro 7 14IMH9

2026-04-22T11:18:49+00:00

[ Upstream commit 217d5bc9f96272316ac5a3215c7cc32a5127bbf3 ] The Lenovo Yoga Pro 7 14IMH9 (DMI: 83E2) shares PCI SSID 17aa:3847 with the Legion 7 16ACHG6, but has a different codec subsystem ID (17aa:38cf). The existing SND_PCI_QUIRK for 17aa:3847 applies ALC287_FIXUP_LEGION_16ACHG6, which attempts to initialize an external I2C amplifier (CLSA0100) that is not present on the Yoga Pro 7 14IMH9. As a result, pin 0x17 (bass speakers) is connected to DAC 0x06 which has no volume control, making hardware volume adjustment completely non-functional. Audio is either silent or at maximum volume regardless of the slider position. Add a HDA_CODEC_QUIRK entry using the codec subsystem ID (17aa:38cf) to correctly identify the Yoga Pro 7 14IMH9 and apply ALC287_FIXUP_YOGA9_14IMH9_BASS_SPK_PIN, which redirects pin 0x17 to DAC 0x02 and restores proper volume control. The existing Legion entry is preserved unchanged. This follows the same pattern used for 17aa:386e, where Legion Y9000X and Yoga Pro 7 14ARP8 share a PCI SSID but are distinguished via HDA_CODEC_QUIRK.
