Hi Takashi,

                    {0x20, AC_VERB_SET_PROC_COEF, 0x00b1},
                    {}
            }
    },

Could I put code as upper? Was it enter to initial state? I think it should be execute atfter resume back. Right?

Yes, these are performed at resume. But the COEF stuff needs a bit care since it's written in multiple places. If you can cook up the patch, I can check it hda-emu, too.

thanks,
