Here's my evtest result:

root at neo:~# evtest  /dev/input/jack 
Input driver version is 1.0.1
Input device ID: bus 0x0 vendor 0x0 product 0x0 version 0x0
Input device name: "gta04 Headset Jack"

"watch -n 0.2 -d cat /sys/class/hwmon/hwmon0/device/in7_input" gives
around 31 with nothing in the headset jack, and 852-857 when the headet
jack is plugged in.

The headset has a small button on it, but pressing it has no effect on
the watch value, and doesn't cause evtest to report anything new.

Regards,
        Neil
