[alsa-devel] Sending headset insertion events to user space on bootup

I’m having an issue passing events when a headset is inserted upon
bootup. I’m sending a headset insertion event to user space through
snd_soc_jack_report, but user space is not yet ready to receive events
and therefore misses the event. Since the kernel driver doesn’t resend
this event, then there’s no way for user space to see it. User space is
still booting up when the event is sent.
Does anyone know of a solution so user space can receive headset
insertion events on bootup?
Is is possible to either allow the kernel to postpone sending events
until user space is ready or to store events in some sort of cache so
that user space can access them? Would it be possible to use ALSA to
store the headset status in a device node?
