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

I confirm. Very strange bug. I've opened the issue then found your description.
What should I do?

I'll try to deattach the video card and test without it. The system will
have only one physical output.

Logged the pulseaudio log. What should I do now? I can reproduce the bug
on a clean live-dvd image.
