ALSA: hda/realtek - Dell headphone has noise on unmute for ALC236



headphone have noise even the volume is very small.
Let it fill up pcbeep hidden register to default value.
The issue was gone.

Fixes: 4344aec8 ("ALSA: hda/realtek - New codec support for ALC256")
Fixes: 736f20a7 ("ALSA: hda/realtek - Add support for ALC236/ALC3204")
