I've discussed the problem in more detail [1] before sending the patch. In short, speakers seems to reliably work in live Ubuntu which differs in using initrd with modules vs UEFI stub with built-in drivers in my case (I've tried Ubuntu kernel sources). I've tried using modules as well (modprobe'ing the list of modules which are load by Ubuntu) with no success. It was suggested that there is a timing issue somewhere. I'm opened for ideas to try to debug the problem origins further (to avoid the need in the fixup). > > > If the issue only happen to warm boot, please try reverting commit > > > 9d3fcb28f9b9 "Revert "PM: ACPI: reboot: Use S5 for reboot"". > > > Many HP systems requires it to have a functional reboot. > > If possible, please still give that commit a try. Well, the first cold boot (with this commit reverted) didn't have any sound, the same goes for the subsequent reboot. [1] https://lkml.org/lkml/2022/1/12/221
