Hi Takashi,
 
I tested your patch and it doesn't work.
I checked caps from nodes 0x04 and 0x05 and comparing with  
http://download.intel.com/standards/hdaudio/pdf/hda034-a2.pdf. document.
The configuration is 4 full HDMI codec not 4 2-channels pcm codec. It
have CP-flag, ext-channel and in pin-widget that HDMI-flag.
