your alc888 have two digital outs

the previous implementation

The multiple outputs are handled as slave streams, so only one PCM stream (and 
the corresponding IEC958*
elements) is provided to control both digital outputs. 


HDMI - OK (simultaneously with S/PDIF)
 S/PDIF - OK (simultaneously with HDMI)

e.g. you can use hint

indep_hp=1

by early patching to crdate the alt analog device 2 for the headphone

When "IEC958 Default PCM" switch is on, the PCM stream is routed both to
analog and SPDIF outputs.

sound is routed to analog, spdif and hdmi in your case

those HDMI 1.3 support Jack detection

graphic driver get HDMI TV 's EDID and pass ELD to audio driver

you have to ask tiwai how to solve your case by providing the working
and non working alsa-info


it is possible to split into two digital devices 1 and 3 so that you can play 
different audio to HDMI  and S/PDIF if the hda controller support four SDO 
playback streams but will lost the capabitiy of playing audio to HDMI and spdif
