I am adding more complete technical information for this issue. Machine - HP Pavilion All-in-One Desktop 32-b0xxx - Board: HP 892C - BIOS: F.19 (08/11/2025)
Audio hardware - Intel Alder Lake-S HD Audio Controller [8086:7ad0] - Realtek ALC274 - Codec subsystem id: 0x103c892c - Two ACPI speaker amp devices: CSC3551:00 and CSC3551:01 Problem - Internal speakers work in Windows. - Internal speakers do not work in Linux. - This is specifically an internal speaker issue. Kernel tested - 6.19.10-1-MANJARO What I observed The two CSC3551 devices are instantiated correctly from ACPI, but cs35l41-hda fails to probe for both of them. After that, the Realtek codec ends up with no speaker outputs enabled. Relevant kernel log lines: Serial bus multi instantiate pseudo device driver CSC3551:01: Instantiated 1 I2C devices. Serial bus multi instantiate pseudo device driver CSC3551:00: Instantiated 1 I2C devices. cs35l41-hda i2c-CSC3551:01-cs35l41-hda.0: probe with driver cs35l41-hda failed with error -524 cs35l41-hda i2c-CSC3551:00-cs35l41-hda.0: probe with driver cs35l41-hda failed with error -524 snd_hda_codec_alc269 hdaudioC0D0: ALC274: picked fixup for PCI SSID 103c:0000 snd_hda_codec_alc269 hdaudioC0D0: autoconfig for ALC274: line_outs=1 (0x17/0x0/0x0/0x0/0x0) type:speaker snd_hda_codec_alc269 hdaudioC0D0: speaker_outs=0 (0x0/0x0/0x0/0x0/0x0) Codec information - Codec: Realtek ALC274 - Vendor Id: 0x10ec0274 - Subsystem Id: 0x103c892c What I already tried - Removed all local snd-hda-intel model overrides - Removed hdajackretask early patch / patch firmware overrides - Tested with a clean ALSA/HDA configuration - The behavior remained the same ACPI findings I dumped and decompiled the ACPI tables. There is an SSDT that defines two speaker devices: - Device (SPK1), _HID "CSC3551", _UID 0, I2C address 0x36 - Device (SPK2), _HID "CSC3551", _UID 1, I2C address 0x37 For both devices, _CRS contains I2C + Interrupt resources. For both devices, _DSD currently exposes only: - cirrus,dev-index - cirrus,speaker-position - cirrus,boost-type I do not see additional GPIO-related device properties in _DSD for these speaker amp devices. This looks like a board-specific support gap for HP subsystem 103c:892c in the HDA/Cirrus path, or an incomplete ACPI description for the CSC3551/CS35L41 smart amps. The important point is that the speaker amp devices are present, but cs35l41-hda does not complete probe, and internal speakers remain unavailable. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1982483 Title: No sound from built-in speakers HP Pavilion All-in-One Desktop 27-ca1xxx (ALC274) To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1982483/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
