This disables snooping mode.  It's rather a problem of controller, not
the codec chip.  There can be a slight performance decrease.

Looking at alsa-info.sh, it's a new chip, and the workarounds for
Intel PCH & co aren't applied to it yet.  That's the likely problem. 
Could you try the patch below without snoop=0 option?
