audio_frames = runtime->status->hw_ptr+ runtime->delay;audio_nsecs = audio_frames * 1000000000LL /runtime->rate;This looks like a 64-bit division.
And what happens if audio_frames becomes negative?
It's my understanding that hw_ptr represents the cumulative frames played since the beginning, not sure why it'd become negative, ever. I know this deserves more love, I don't understand the notion of 'boundary' and the use of the hw_ptr_base, I figured smarter people than me would help. Thanks, -Pierre
