Since SPDIF support for the auixp driver is still half done
disable it for now since some chipset revisions will freak out
on the aparent half-initialisation.
Also delay the setting of the DMA bits until after the codec
detection but before the enabling of interrupts. Note that the
DMA has to be explicitly started when the device is opened.
