From: Takashi Iwai <tiwai@xxxxxxx> 3.12-stable review patch. If anyone has any objections, please let me know. =============== commit 8e38395360844806041ea69ab9690f5f174bc40c upstream. ASUS N56VZ and N76VZ laptops have a bass speaker but its output comes only from the right channel. This patch adds the extra chmap specific to these models.
