Subject: Is there a function I can call from my ISR to tell ALSA to abort playback?
Date: Wed, 14 Nov 2007 14:41:39 -0600 [thread overview]
Message-ID: <473B5D83.2020408@freescale.com> (raw)
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?
