Unfortunately, this soundcard will not do full-duplex. Most onboard audio
controllers are not capable of this. I would definitely recommend getting
a PCI soundcard like the SoundBlaster PCI128.

I too spent quite a lot of time testing soundcards and have found that the
SoundBlaster PCI128 (even though its considered old) works like a champ.
Even the kernel level OSS sound module will do full-duplex so I didn't
need to buy a license from 4Front.
