Kernel log shows repeated Failed waiting for CS35L41_PUP_DONE_MASK: -110 errors 5–6 seconds after boot, triggered on first audio playback. Root cause: SSDT16 (_ASUS_/SPKRAMPS) defines cirrus,boost-type = 1 (external boost) for SSID 10431A63. The CS35L41 VSPK supply is controlled by an external GPIO (GPI0 pin 0x48 / Linux GPIO 584 on INTC1083:00, CRS resource index 0 in the SPK1 device). The driver has no regulator mapped to this GPIO and falls back to a dummy regulator. regulator_enable() becomes a no-op — VSPK is never re-enabled after a runtime power cycle. At cold boot the BIOS leaves VSPK HIGH, so the initial driver probe succeeds. On first playback, the driver's playback hook power-cycles the amps; VSPK is not re-enabled; PUP_DONE_MASK times out. ACPI path: \_SB.PC00.SPI1.SPK1 Relevant GPIO (VSPK enable): GPI0 pin 0x48, output, PullUp — present in _CRS but not referenced in _DSD Reset GPIO: GPI0 pin 0xD0, output, PullDown Kernel log (failure): cs35l41-hda spi0-CSC3551:00-cs35l41-hda.0: Using extra _DSD properties, bypassing _DSD in ACPI cs35l41-hda spi0-CSC3551:00-cs35l41-hda.0: Cirrus Logic CS35L41 (35a40), Revision: B2 cs35l41-hda spi0-CSC3551:00-cs35l41-hda.0: CS35L41 Bound - SSID: 10431A63, BST: 1, VSPK: 1, CH: L, FW EN: 1, SPKID: 1 cs35l41-hda spi0-CSC3551:00-cs35l41-hda.0: Failed waiting for CS35L41_PUP_DONE_MASK: -110 Workaround (audio works but speaker protection firmware disabled): echo "options snd_hda_scodec_cs35l41 firmware_autostart=0" > /etc/modprobe.d/cs35l41-nofw.conf With firmware_autostart=0: FW EN: 0, no PUP_DONE_MASK errors, audio works. Required fix: Add a proper GPIO regulator mapping for the VSPK supply (GPI0 pin 0x48) for SSID 10431A63 in cs35l41-hda-property.c, so the driver can properly re-enable VSPK during runtime power cycles.
