Comment # 38 on bug 928394 from Foulques du Peloux

Sorry for the late reply. The main problem is still not fixed and I did some
additional tests to have some more clues.

When I start my computer with the headphone plugged-in, I have no sound.
If I unplug the headphone and plug it again, this "fix" the sound. But every
time I restart my computer I have to do this.

If I start my computer without the headphone and I plug it in after the desktop
session is opened, sounds works properly.

In general, my speakers are always working without issue, the only problem is
the headphone jack since the last update (before this alsa-utils one).
