The other problem is this patch

   { .id = 0x10ec0892, .name = "ALC892", .patch = patch_alc662 },

http://git.alsa-project.org/?p=alsa-kernel.git;a=commit;h=274693f37090ada2cadd09944ab883f05ea6ebe6

ALC892 provides ten DAC channels that simultaneously support 7.1 channel
sound playback, plus 2 channels of independent stereo sound output (multiple
streaming) through the front panel stereo outputs.

It seem  that there is no specific code to distinguish a 10 channels alc892
from those 6 channels alc6xx
