I've reported the bug at kernel bugtracker. The fix would be included in 
3.18-rc5. You can also use workaround like this:
apt-get install alsa-tools
root@meklon-desktop:/home/meklon# hda-verb /dev/snd/hwC0D2 0x20 SET_COEF_INDEX 
0x07
nid = 0x20, verb = 0x500, param = 0x7
value = 0x0
root@meklon-desktop:/home/meklon# hda-verb /dev/snd/hwC0D2 0x20 SET_PROC_COEF 
0x7cb0
nid = 0x20, verb = 0x400, param = 0x7cb0
value = 0x0

Please change the bug status to fixed or mark it in any way.
