After some amount of hackery, I've managed to make this work for
sending audio from mpd on my server. It's not quite as trivial as your
other examples make it look though. Because 'tx' only receives audio
from CAPTURE devices, you have to use snd-aloop to create a loopback
audio device that mpd can play into, for tx to capture from. The
sequence here is

  $ modprobe snd-aloop
  $ tx -d hw:1,1 ...

then get mpd to play into

  audio_output {
    type            "alsa"
    name            "My ALSA Device"
    device          "hw:1,0"
  }

The non-obvious trick here is to play mpd into hw:1,0 but capture tx
from hw:1,1

If you'd like I could write you up something to add to your web page,
to assist people in this one.
