Hello all,

             I am rendering audio to a PCM playback device (hw:0,0). I also need to render the same audio data to second PCM playback device (hw:0,1).

1) Can i use ALSA mixer APIs so that i give PCM audio data to 1 playback device or some common interface,
    but the PCM audio data is rendered to both devices (hw:0,0 and hw:0,1)
