snd_hda_intel apply treat differently hda intel hardware differently depending 
on device id.

Explore a little bit files content under /proc/asound

Such as:

/proc/asound/cards
/proc/asound/devices
/proc/asound/pcm
/proc/asound/card0/codec*

Fallback to simple stuff such as

speaker-test -c2

aplay somewavfile.wav
aplay -l
aplay -L

I have found it useful and very interesting to do

strace -e trace=open speaker-test -c2

That shows you all config files that alsa-lib opens.
