This is exactly the problem with this codec (actually with all
unsupported CXT modem codecs).

No, afaik.

If you (as reference hw holder) can find how to hook-off this codec
this may help (I think some works should be done with 0x7a AC97
registers, but not something trivial, it is likely just pipe which pass
data to codec and DAA internal parts).

Also I'm pretty sure that 'hook-off' is only one visible problem there.
