OK.  The fallback to the single_cmd happens usually when invalid
access to the codec chip occurs.  In most cases, the verbs sent by the
static model don't match with the actual hardware.  Or, the verbs are
sent in the bad power-state (e.g. during PM).  Or whatever strange
reason.

In this particular case, the verb 0x0070503 is really wrong
(i.e. NID=0).
