I was too, but figured it out. I use kphone to talk to an Asterisk
software PBX, also running under NetBSD. :-)

I ended up with the following in my rc.local -- this is all I do to
the audio configuration; apart from this, I just use the buttons on
the keyboard to adjust output volume.
/usr/sbin/audioctl -w record.port=1
/usr/sbin/audioctl -w record.gain=240
This way, kphone works with or without ear plugs -- but it's more
pleasant to use with them, of course.
