Does it mean I have to open "plughw:0,0,0", "plughw:0,0,1"...or
"plug:dmix" ?
        I did not find any doc about device name with snd_pcm_open, and
aplay -l does not list anything
like plughw, etc...

        If I open "plughw:0,0,0", "plughw:0,0,1" for my via 686b, will it
continue to work on other soundcard
in the same way (with multiple stream with different format) ?

        Thanks,

David
