 I want to keep same behavior with alc_fixup_thinkpad_apci() and alc_fixup_idea_acpi() for one sound card. So, I add alc_fixup_no_shutup() in alc_fixup_ideapad_acpi().
----------Related source code of patch_reatek.c are FYR as below.
static void alc_fixup_thinkpad_acpi(struct hda_codec *codec,
                                     const struct hda_fixup *fix, int
action)
{
         alc_fixup_no_shutup(codec, fix, action); /* reduce click noise */
         hda_fixup_thinkpad_acpi(codec, fix, action); }

/* for hda_fixup_ideapad_acpi() */
#include "ideapad_hotkey_led_helper.c"

static void alc_fixup_ideapad_acpi(struct hda_codec *codec,
                                    const struct hda_fixup *fix, int action) {
         alc_fixup_no_shutup(codec, fix, action); /* reduce click noise */
         hda_fixup_ideapad_acpi(codec, fix, action);
}
