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?
BR,
Kailang
