Thanks Kailang, I applied the patch and it works.
I attached again the diffs, before and after PM (with `echo 1 >
/sys/modules/snd_hda_codec/parameters/dump_coef`) so you can see the
coefs have the same values.
OK, I queued the patch now.  Not sure whether this will be in 4.3
final, but certainly included in 4.4-rc1.
thanks,
Takashi

Attach is the patch.
Looks good to me.
I'm going to queue it once when George confirms that it works indeed.
thanks,

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
