This is exactly what I did now:

It gives me the multi-io config without side effects and without the
hp_lo_shared and spk_lo_shared issue in get_line_out_pfx().

I'd like to make this configurable for people suffering from the same problem
with their ALC662, but I don't know how to identify when it would occur.
