Hi Takashi,
    [ALC275_FIXUP_DELL_XPS] = {
            .type = HDA_FIXUP_VERBS,
            .v.verbs = (const struct hda_verb[]) {
                    /* Enables internal speaker */
                    {0x20, AC_VERB_SET_COEF_INDEX, 0x1f},
                    {0x20, AC_VERB_SET_PROC_COEF, 0x00c0},
                    {0x20, AC_VERB_SET_COEF_INDEX, 0x30},
                    {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,
Takashi
