Well, in this case, the codec probe itself fails, so we cannot get the
mostly userful information such as codec#* proc files.  Thus it won't
be helpful to give such instructions.

I suspect this particular case is rather an ACPI problem like others.
Some ACPI-related boot options are worth to try...
