66 * calling SNDRV_COMPRESS_SET_PARAMS. Running streams will come to this
67 * state at stop by calling SNDRV_COMPRESS_STOP, or at end of drain.
68 * SNDRV_PCM_STATE_PREPARED: When a stream has been written to (for
69 * playback only). User after setting up stream writes the data buffer
70 * before starting the stream.
71 * SNDRV_PCM_STATE_RUNNING: When stream has been started and is
72 * decoding/encoding and rendering/capturing data.
73 * SNDRV_PCM_STATE_DRAINING: When stream is draining current data. This is done
74 * by calling SNDRV_COMPRESS_DRAIN.
75 * SNDRV_PCM_STATE_PAUSED: When stream is paused. This is done by calling
76 * SNDRV_COMPRESS_PAUSE. It can be stopped or resumed by calling
77 * SNDRV_COMPRESS_STOP or SNDRV_COMPRESS_RESUME respectively.
