### ๐ Audio broken with Broadwell-RT286 on Ubuntu 24.04 (Kernel 6.11.0-29-generic)
#### ๐ Summary After upgrading to Ubuntu 24.04 (kernel `6.11.0-29-generic`), the internal speakers of my notebook using the `broadwell-rt286` audio chip no longer work. Only headphone output functions correctly. Internal audio playback is completely silent. #### ๐ก Details - `aplay -l` detects the device as `broadwell-rt286` - PulseAudio/PipeWire only shows a `null-sink` (no actual hardware output) - Module `snd_soc_sst_broadwell_rt286` is missing from `/lib/modules/6.11.0-29-generic` - On Ubuntu 22.04 (with kernel 5.15 or 6.5), everything worked correctly โ the internal speakers were functional #### ๐ ๏ธ Suggested Fix Please ensure the following kernel configuration options are enabled in Ubuntu 24.04 kernels: CONFIG_SND_SOC_INTEL_SST_TOPLEVEL=m CONFIG_SND_SOC_SST_BROADWELL_RT286=m CONFIG_SND_SOC_INTEL_BDW_RT286_MACH=m CONFIG_SND_SOC_RT286=m These were previously present in older Ubuntu kernels and enabled full sound support for many laptops with Intel Broadwell-based audio hardware (e.g., some Lenovo, Toshiba, Asus models). #### ๐งช Temporary workaround Using headphones works as a fallback. But internal audio remains broken unless the correct modules are re-enabled in the kernel. #### ๐ System Info - Ubuntu 24.04 LTS - Kernel: `6.11.0-29-generic` - Audio: `broadwell-rt286` (Realtek RT286 via Intel SoC) - Module `snd_soc_sst_broadwell_rt286` cannot be loaded (`modprobe: FATAL: Module ... not found`) --- Please consider re-enabling these modules in future kernel builds.
