Since pulse audio only pay attention to the Master mixer of the primary card. The Thinkpad EC shows up basically as a second audio card. But again new Thinkpads don't need this. Since they send a soft keypress by default. So userspace catches it and changes the Master mixer to mute. I think all this work isn't going to help the situation any. There appears to be a easy solution. Just a matter of getting the LEDs on some to light correctly, and see when the hardware mute is enabled.
