Public bug reported: Missing ACPI ID CLSA0102 for CS35L41 driver — Lenovo Yoga Slim 7 Carbon 14ACN06
Adding a data point for this laptop family. Same underlying issue as the CLSA0100/CLSA0101 cases already patched, but with a newer, still- unsupported ACPI ID. System: Model: Lenovo Yoga Slim 7 Carbon 14ACN06 (Product Name 82L0) Kernel: 7.0.0-30-generic (Ubuntu 24.04-based) Distro: Linux Mint 22.3 The gap: My laptop's amp reports ACPI ID CLSA0102: $ ls /sys/bus/acpi/devices/ | grep -iE "csc|clsa" CLSA0102:00 But the installed snd_hda_scodec_cs35l41_i2c module's alias table only covers: $ modinfo snd_hda_scodec_cs35l41_i2c | grep -A5 alias alias: acpi*:CSC3551:* alias: acpi*:CLSA0101:* alias: acpi*:CLSA0100:* As a result, the driver never attempts to bind at all — dmesg | grep -iE "cs35l41|cirrus" returns nothing, and the module doesn't even appear in lsmod. This isn't a firmware-loading failure; the device is never recognized in the first place.

Given the precedent of the CLSA0101 patch (https://lkml.iu.edu/hypermail/linux/kernel/2207.3/03031.html), adding CLSA0102 support looks like a similar, well-scoped addition — happy to test any patch or provide further diagnostics.
