Comment 751 for bug 1958019

I own a Lenovo Legion Slim 7 Intel 16IAH7 with the same issue (no speaker sound but headphones ok).

Alsa-info for this particular machine can be found here: http://www.alsa-project.org/db/?f=9f1deb511b2604f1b52a7905889deb4463ca9211.

Would these alsa-info be enough for someone to create a patch for this model? If not, I'm ok to spend some time on the issue. I have no particular knowledge on how fixups are implemented but patching and compiling the kernel is not an issue. Probably I can take example on existing fixups to implement a new one. If so, some pointer on documentation or resource on where to start would be much appreciated.
