[Bug 2170415] Re: ASUS Zenbook 14 UM3405GA: internal speakers silent, CS35L41 amps probed but not bound (ALC294, subsystem 1043:19f4)

It may need a quirk ALC294_FIXUP_CS35L41_I2C_2 for this machine. Could you post the output file of `sudo alsa-info` so the descriptive “ALSA/HDA dmesg” would help further information?

Hardware: ASUS Zenbook 14 UM3405GA, Ryzen AI 9 465 OS: Ubuntu 26.04 LTS, kernel 7.0.0-38-generic BIOS version: UM3405GA.304 Problem: Internal speakers produce no sound. Headphone jack, HDMI audio and Bluetooth audio work. Findings: - Codec: Realtek ALC294, Subsystem ID 0x104319f4 - ACPI device CSC3551 is present. dmesg shows two Cirrus Logic CS35L41 amps (Revision B2) detected by cs35l41-hda: cs35l41-hda i2c-CSC3551:00-cs35l41-hda.0: Cirrus Logic CS35L41 (35a40), Revision: B2 cs35l41-hda i2c-CSC3551:00-cs35l41-hda.1: Reset line busy, assuming shared reset cs35l41-hda i2c-CSC3551:00-cs35l41-hda.1: Cirrus Logic CS35L41 (35a40), Revision: B2 - The codec driver logs "picked fixup (pin match)", meaning no model-specific quirk is applied. - The kernel already contains ALC294_FIXUP_CS35L41_I2C_2, which looks like the right fixup, but 0x104319f4 doesn't appear to be in the quirk table. - linux-firmware 20260319 has no cs35l41-dsp1-spk-prot-104319f4 tuning files. - speaker-test -D hw:1,0 is silent. alsamixer shows nothing muted except headphones. PipeWire shows a correct default sink. - fwupd has no System Firmware update for this model. Request: please consider adding a quirk entry for 1043:19f4 using the CS35L41 I2C fixup, and tuning files if available. I can test patches or test kernels.
