Thanks.

T440 support headset and thinkpad pro dock combo jack has headset icon

If headset mic has higher priority than dock headset mic, it is strange
that headset don't auto mute dock headset

So headphones should automute between each other if and only if both of them are combined headset jacks? Or what do you suggest?
