I'm encountering some troubles with my F29 machine (Clevo N170RD) and the headphones jack.

After a fresh boot everything works fine.
Speakers and headphones are both working and switching whenever the jack is plugged/unplugged.

However after resuming from sleep I can only get sound from the speakers.

I've checked Alsamixer and it looks like it makes the switch correctly from the speakers to the headphones.
I can actually see the full 100% volume in the "headphones" column and that it mutes the speakers. But there is still no sound coming out of the jack...

I've searcher through the forums but everything seems to come back to pulseaudio and alsa. I'm pretty convinced that the problem doesn't come from there though...

Do anyone have a clue of what could be causing this?
