The ALSA framework will stop the stream and return the error code EIO when there was no interrupt for ten seconds, i.e., when snd_pcm_period_elapsed() was not called.
I am getting the interrupts, but why there wont be any interrupt for 10 seconds?
I don't quite understand this sentence. You do get interrupts? And snd_pcm_period_elapsed() is not called?
I am setting the periods in prepare as periods = runtime->period, so interrupts should at period boundaries.
runtime->periods is the number of periods. I don't know how your hardware works, but I guess it wants to know the period size, i.e., runtime->period_size converted to bytes.
