Public bug reported: On Ubuntu Mainline Kernel 6.15.4-061504-generic, the kernel configuration contains:
CONFIG_SND_SOC_INTEL_SOUNDWIRE_SOF_MACH=m However, the compiled kernel module `snd_soc_intel_soundwire_sof_mach.ko` is missing from the installed package: linux-modules-6.15.4-061504-generic This module is required for audio functionality on Intel platforms using SOF + SoundWire (e.g. Lunar Lake, Meteor Lake), including: - Intel Lunar Lake SoC - CS42L43/CS35L56 codec combinations - ThinkPad X9 Gen 1 and similar hardware Without this module, affected systems have no audio devices except "Dummy Output". --- **Expected behavior**: - The module should be included in the package and available under: /lib/modules/6.15.4-061504-generic/kernel/sound/soc/intel/boards/ **Actual behavior**: - The module is missing. - `modinfo` fails with: modinfo: ERROR: Module snd_soc_intel_soundwire_sof_mach not found. --- **Steps to reproduce**: 1. Install 6.15.4 from https://kernel.ubuntu.com/mainline/v6.15.4/ 2. Reboot into kernel 6.15.4-061504-generic 3. Run: modinfo snd_soc_intel_soundwire_sof_mach --- **Impact**: This module is required for proper SOF SoundWire audio support on modern Intel hardware. Several distributions (Fedora, Arch) include this module by default. Without it, mainline kernels are incomplete for current-generation laptops and embedded devices. Please include the compiled module `snd_soc_intel_soundwire_sof_mach.ko` in future linux-modules-* packages when CONFIG is set to `=m`.
