### ๐Ÿž Audio broken with Broadwell-RT286 on Ubuntu 24.04 (Kernel
6.11.0-29-generic)

#### ๐Ÿ“Œ 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.

#### ๐Ÿ’ก 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

#### ๐Ÿ› ๏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).

#### ๐Ÿงช Temporary workaround

Using headphones works as a fallback. But internal audio remains broken
unless the correct modules are re-enabled in the kernel.

#### ๐Ÿ“Ž 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. Thank
you!
