auich(4)
eso(4)
azalia(4)
eap(4)
emu(4)
cmpci(4)
clcs(4)
and others, but these I have tested (in -current).
now, there are different ways of doing full-duplex, and some methods
work better than others. so, even if full-duplex is possible, the
way it is implemented makes a difference. take a look at
src/regress/sys/dev/audio_rw/audiotest_rw.c. read the commit messages
for that and pay close attention to audio(4).
also note that with azalia(4) and the ac97(4) based devices, some codecs
may work better than others.
