http://git.kernel.org/?p=linux/kernel/git/tiwai/sound-2.6.git;a=commit;h=1304ac8993e32c0530bc82bf1d3f953548a20971

I guess the driver still need to provide init_verbs for alc892 for the side
channel mixer 0x0f since alc662_parse_auto_config() use different init_verbs
for different codec

especially alc662_init_verbs

send: NID=0x15, VERB=0x70c(set_eapd_btl), PARM=0x2
EAPD command to non-capable pin 0x15
