Well, many in-kernel sound card drivers also do full-duplex.  The issue, 
however, is that the ALSA drivers generally works better for older (or very 
new) cards.  A bunch of cards that don't work in full-duplex mode with the 
kernel drivers work with ALSA.  That's the only reason it's recommended to 
install it.

It's not really necessary anywhere except where the kernel sound drivers don't 
work.
