Hi Gilles,
hopefully this is the right place for this question. I've fruitlessly been trying to get sound to work on the Intel NUC M15 https://linux-hardware.org/?probe=93690f8eec. A fitting topology for this platform seems lacking, among other things. Is there any work ongoing on this? I will gladly provide diagnostic data from my system, if so desired.
The information provided seems to match a supported platform:
Tiger Lake-LP Smart Sound Technology Audio Controller sound snd_hda_intel, snd_sof_pc...
Such TGL-LP devices are tested by our CI, so it's likely a distro/installation issue.
You may want to take a look at https://thesofproject.github.io/latest/getting_started/index.html#debug-audi... for suggestions on debugging, and if that doesn't succeed open an issue at https://github.com/thesofproject/linux/issues (attach the result of alsa-info)
Thanks -Pierre
