If you look in the file drivers/acpi/blacklist.c .. you will should see T400 as part of that list toward the bottom of the file. The reason for this is the kernel sends it OSI(Linux) so the bios will send a mute key press. If you are not seeing this behavior update your bios. Though you shouldn't have to, I think it's the only reason your not seeing the mute key generate a mute key press.
