The issue is definitely not limited to warm boots only. I can confirm cold boots with no sound and also warm boots with functioning sound. With this in mind, the provided numbers (16 good boots across 709 boots) are largely coming from reboots since the testing was scripted and driven by SSH. > 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. Interesting. I haven't noticed anything breaking with reboots on this particular system (at least so far).

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

There are several PCI ids associated with HP EliteBook 855 G8 Notebook PC. Commit 0e68c4b11f1e6 ("ALSA: hda/realtek: fix mute/micmute LEDs for HP 855 G8") covers 0x103c:0x8896, while this commit covers 0x103c:0x8895 which needs some additional work on top of the quirk from 0e68c4b11f1e6. Note that the device can boot up with working speakers and micmute LED without this patch, but the success rate would be quite low (order of 16 working boots across 709 boots) at least for the built-in drivers scenario. This also means that there are some timing issues during early boot and this patch is a workaround. With this patch applied speakers and headphones are consistenly working, as well as mute/micmute LEDs and the internal microphone.
