what kind of PCM device ? since users can define their own "default" device

1) hw:0,0
2) plughw:0,0
3) dmix:0 
4) pulse

For hw:0,0 and plughw:0,0 , only those hardwaremixing sound with multiple
subdevices ( snd_pcm_info_get_sudevice_count() > 0 ) support multiple open

but need to add IDsDriverBufferImpl *secondary[16] for each hardware secondary
buffer ( ALSA subdevice )

struct IDsDriverImpl
{
    /* IUnknown fields */
    const IDsDriverVtbl *lpVtbl;
    LONG ref;

/* IDsDriverImpl fields */
    IDsDriverBufferImpl* primary;
    UINT wDevID;
};
