If the real machine has N audio cards chances that they are routed
through the same mixer are zero, in other words each and every one has
it's own volume controls/mute state etc.

As for "real mixer" support then i must note that it's nearly
impossible to get this thing working correctly, it's more of an
annoynace than benefit.
