In this example, it is said:

So removing the middle box may be recommended :-)

Then, next issue on sound: 
With real audio sink,
 Audio -> Audio sink
is connected as an output, you may get

| INFO: Audio sink arch: alsa
| ALSA lib pcm.c:2243:(snd_pcm_open_noupdate) Unknown PCM /dev/audio1
|  ... (several repeated lines) ...
| assertion "pcm" failed: file "pcm.c", line 729, function "snd_pcm_nonblock"

This is probably because ALSA does not work well on NetBSD
(or my emulation setup is not good).
I'm testing the without-ALSA version at wip/gnuradio-core,
and seems better. (Better means sound comes out but not smooth).
portaudio is used for me now.
