ALSA hits trigger method in my driver and soon after it leaves my trigger method throws an null pointer exception

What code hits a NULL pointer?

I am wondering if the ALSA will call SNDRV_PCM_TRIGGER_START every single time new buffer is available.

No, once the stream is started, ALSA expects the device to run by itself (if not, the driver has to use timers).
