I have the Asus M3N78-EM which is very similar to the mobo mentioned
above and have been able to switch between the two audio outputs using
alsa by simply changing the entries in /etc/asound.conf.

I needed to add the following entry at the end of the file
/etc/modprobe.d/alsa-base

options snd-hda-intel model=6stack-dig

Without it, I could not get the port to light...

my /etc/asound.conf is below and I can switch between audio ports by
changing the entry "hw:0,1" to "hw:0,3"

---start file----
pcm.dmixer {
   type dmix
   ipc_key 1024
   ipc_key_add_uid false
   ipc_perm 0660
   slave {
      pcm "hw:0,1"
      rate 48000
      channels 2
      format S32_LE
      period_time 0
      period_size 1024
      buffer_time 0
      buffer_size 4096
   }
}

pcm.!default {
   type plug
   slave.pcm "dmixer"
}
---end file----

Cheers
