It looks like HDA intel audio is incorrectly detected as Conexant CX20561

It turned out to be a PulseAudio bug which wrongly detects headphone as plugged-in and set Speaker Volume to 0% and Headphone Volume to 100%

Comment 5 Rex Dieter 2014-08-09 19:28:43 UTC
If so, I'd strongly suggest taking this upstream to bugzilla.freedesktop.org pulseaudio component.

Comment 6 Ionut Radu 2014-08-09 19:34:18 UTC
I'm not sure yet if it's PulseAudio bug or alsa bug. PulseAudio gets a notification from alsa about headphone plugged-in or unplugged. Maybe the notifications from alsa are not good.

It solved itself.
