If I enable AC3, I get a loud clicking sound and nothing else.  If I enable the five speaker setup, I only get stereo sound from my front left and right speakers.  I have tried using alsa name set as default, pcm, surround51, and iec958.  At one point I was getting only the front left and right surround channels, and was missing the center front voice and rear surround channels.

You should use 


     <alsa>
        <name>iec958:AES0=0x2,AES1=0x82,AES2=0x0,AES3=0x2</name>
     </alsa>
and
   <speakers>
     <channel_config>
        <chtype>AC3</chtype>
     </channel_config>
     <channel_config>
        <chtype>DTS</chtype>
     </channel_config>
     <channel_config>
        <chtype>MPEG</chtype>
     </channel_config>
     <channel_config>
        <chtype>LPCM</chtype>
     </channel_config>
   </speakers>

if the iec958 output target is present.  Though you might need to use a mixer
to enable SP/DIF output on the card. 

This will send raw undecoded data out via SP/DIF to your external reciver.

If this wasn't want you wanted you'll have to explain in more detail...

For analog multi channel output

  <audio>
    <device>
      <driver>alsa</driver>
      <path>/dev/dsp</path>
      <alsa>
        <name>surround51</name>
      </alsa>
    </device>
    <speakers>
      <channel_config>
        <chtype>Left</chtype>
        <chtype>Right</chtype>
        <chtype>RearLeft</chtype>
        <chtype>RearRight</chtype>
        <chtype>Center</chtype>
        <chtype>LFE</chtype>
      </channel_config>
    </speakers>
