I have tried put "IOID" in many place such as usr/share/alsa/pcm/front.conf
,

it seem that hint_list_add() only add name and description in
alsa-lib/src/control/namehint.c

hint_list_add(struct hint_list *list,
             const char *name,
             const char *description)

I wonder "IOID" was never added to the hint list and that is why all devices
are Input/Output

dsnoop should be input and dmix should be output
