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. > > Partly derived from VirtualBox's mixer support - but cleaner and without > calculation errors. :) > Shrug. -- mailto:av1474@comtv.ru
