PA doesn't see all Alsa devices by default. Exactly why, I'm not going to  
try explain, but the way I was informed:
PA needs a interface it can understand, such as stereo, 5.1, 7.1, etc.
Multichannel devices often are not recognized by PA, and so was the case  
with the ice1712(envy24) chip earlier. Was fixed some time ago.
