Ah, I see, I'll look around but I don't think that such a documentation 
exists.
I suppose that the soundcard is providing the sound and it is routed via 
the video card to give a combined hdmi video+audio feed.

Maybe the trick is to find a way to activate this node (if I only knew how):

Node 0x1b [Pin Complex] wcaps 0x40038d: Stereo Digital Amp-Out
    Amp-Out caps: ofs=0x27, nsteps=0x27, stepsize=0x05, mute=1
    Amp-Out vals:  [0x27 0x27]
    Pincap 0x00000014: OUT Detect
    Pin Default 0x98561150: [Fixed] Digital Out at Int HDMI
      Conn = Digital, Color = Black
      DefAssociation = 0x5, Sequence = 0x0
      Misc = NO_PRESENCE
    Pin-ctls: 0x00:
    Unsolicited: tag=00, enabled=0
    Connection: 1
       0x02
