Public bug reported:
Speakers stay on in Ubuntu 12.04 when headphones are plugged into the jack.
(Acer Aspire 6920G, ICH8 chipset, ALC262 audio). All was working fine in 11.10.
There also appears to be no way to mute the speakers while keeping the
headphones on.
If I boot up with the headphones already in the port, the sound only comes out
of those. However, removing them doesn't make the sound switch to the speakers,
as it used to and as it should.
