Public bug reported:
Since upgrading to Ubuntu 24.04 with kernel 6.11.0-29-generic, internal
audio via the Broadwell-RT286 sound chip no longer works.
Only headphones work. Internal speakers do not produce sound.
The kernel module snd_soc_sst_broadwell_rt286 is completely missing in
/lib/modules, and cannot be loaded.
In Ubuntu 22.04 (e.g., with kernel 5.15 or 6.5), this module was present
and sound worked fine.
Please re-enable the following in the kernel config:
CONFIG_SND_SOC_SST_BROADWELL_RT286,
CONFIG_SND_SOC_INTEL_BDW_RT286_MACH,
and related SOF/ASoC options.
Thank you!
