Subject: ALSA: hda - No loopback on ALC299 codec
From: Takashi Iwai <tiwai@xxxxxxx>
commit fa16b69f1299004b60b625f181143500a246e5cb upstream.
ALC299 has no loopback mixer, but the driver still tries to add a beep
control over the mixer NID which leads to the error at accessing it.
This patch fixes it by properly declaring mixer_nid=0 for this codec.

Fixes: 28f1f9b26cee ("ALSA: hda/realtek - Add new codec ID ALC299")
