The mixer control plugin also accepts the parameters "source" and "sink" for
when you need to specify a sink/source combination with different names. If
you need to do this with PCM:s then specify two PCM:s with different "device".


Does it mean that the application only get playback controls from
sink0, sink1 and capture controls from source0, source1, source2


ctl.sink0 {
    type pulse
    sink "0"
}



ctl.source0 {
    type pulse
    source "0"
}


ctl.sink1 {
    type pulse
    sink "1"
}

ctl.source1 {
    type pulse
    source "1"
}

ctl.sink2 {
    type pulse
    sink "2"
}

ctl.source2 {
    type pulse
    source "2"
}
