When I call snd_jack_report with the status of the jack, am monitoring the /dev/input/eventX (using event.c) for Userspace events when Headset is inserted and I don't see any events even when snd_jack_report() is called. Is there any specific configuration that is required (xorg.config)?

When I call snd_jack_report with the status of the jack, from the user user space which parameter should I check in the sys/class/input/input2 to know if the jack is present or not?
Assuming you're looking to check the presence of a device in the jack (rather than the presence of the jack itself) then there's nothing in sysfs, you read this information from the device node. See evtest.c (google should show up lots of copies) for sample code doing this.
