[alsa-devel] Is there a function I can call from my ISR to tell ALSA to abort playback?

[Timur Tabi]

In my ISR, I call snd_pcm_period_elapsed() to tell it that a period has elapsed. 
  I can also detect if playback has aborted for some reason (e.g. DMA controller 
has died).  Is there a function I can call in my ISR to tell ALSA to abort 
playback or capture?
