As the users reported in https://launchpad.net/bugs/595896, there is no KEY_MUTE either from thinkpad_acpi nor the keyboard when pressing the mute hotkey. (I do not really possess the hardware. but just debugged/helped remotely).
It will be really appreciated if there is any suggestion/insight for looking into the bug. At the moment I can just find this fix for the issue. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
