Boot into vendor BIOS/EFI thing, install and start acpi_listen, then press the mute button. http://linux.die.net/man/8/acpi_listen
I tried that just now. I don't see any events in acpi_listen, when I use the mute button. I do see events for the up/down volume buttons.
The mute button does work (only in factory BIOS), but I don't see any events in the OS. The volume in gnome isn't shown muted, either. I think the mute button might be hardware based, while the volume buttons are software (ACPI).

and take a look on "Interaction with the Embedded Controller" at https://wiki.ubuntu.com/Kernel/Reference/ACPITricksAndTips
you want to know which _QXX function is called. maybe that one is
empty in the coreboot aml for h8s..
Thanks, I'll take a look. It doesn't seem like the mute button is controlled by ACPI, though.
Perhaps I could use ectool (and other utils?) to see what happens when muting.
