This isn't ideal for multi-function jacks like headsets - it will report a single boolean value for the jack regardless of what's plugged in meaning userpace can't do things like figure out if a headset or headphone is present. It's probably OK for any realistic input button since you're not going to get an input button without other things being present.
What I'd expect to happen here is that for multi function jacks we create a control per function if the controls are valid.
