[alsa-devel] 5.1 sound system works as 2.0 on all kernels newer than 3.2.21

[giperon at land.ru]

Hi, my 5.1 sound system works as 2.0 on all kernels newer than 3.2.21.
Control "Channel Mode" is missing in "Alsamixer".
I use the option "3stack-6ch" (module snd-hda-intel, Realtetsk codec ALC882) for kernel 3.2.21.

"Alsa-info" for kernels 3.2.21 and 3.13.6 attached.
