[alsa-devel] SNDRV_PCM_TRIGGER_STOP and audio still queued in the driver

In the mpc5200 driver I'm receiving SNDRV_PCM_TRIGGER_STOP with audio still queued. I noticed this in an app that uses a 2MB ALSA buffer. It is filling the 2MB buffer which starts playing. After the buffer is filled I receive the STOP. This STOP comes before the hardware has a chance to play all of the music. There is still about twenty seconds of music in the driver buffer waiting to be played.

How is this supposed to work?
