Java uses the ALSA sound system, so I'm not sure how NAS would help
unless you can configure ALSA to talk to it.  You could maybe look at
the alsa-sndio port and then configure it to connect to an sndiod
running locally on your machine.  I've never attempted this and I'll
note that alsa-sndio warns it only supports output not input, so that
likely won't help if you need the microphone to actually work.
