Synopsis:

#define SND_AFM_STATE_RUNNING 0x01
#define SND_AFM_STATE_RUNNING_PCM 0x02
#define SND_AFM_STATE_IDLE 0x03
#define SND_AFM_STATE_SHUTDOWN 0x04

typedef struct snd_afm_status
{
    uint64_t    ms_processed;
    uint32_t    state;
}snd_afm_status_t;

Description:

The snd_afm_status_t structure describes the status of an AMP Functional Module (AFM). To get this information, call snd_afm_status().

The members include:

ms_processed

The number of milliseconds of audio that the AFM has processed since it was started.

state

One of the SND_AFM_STATE_* state types:

SND_AFM_STATE_RUNNING — AFM is running using audio provided by a hardware device.
SND_AFM_STATE_RUNNING_PCM — AFM is running using audio provided through its software PCM interface.
SND_AFM_STATE_SHUTDOWN — AFM is shut down.
SND_AFM_STATE_IDLE — AFM is idle.
