I've tried multiple ways to solve my problem as described in other topics in this forum, but none succeeded. The Headphones sound worked when I first installed Ubuntu 12.10, but after a few updates it ceased to function. Sound works fine with the speakers but as soon as I insert the jack, there is nothing but silence. I've checked Alsamixer and when I insert the jack it mutes the speakers but not the Headphones column. I've even tried installing the drivers from Realtek but it was a very bad idea since it crashed my OS completely and I had to re-install everything. I'm a bit on the newbie in this Ubuntu thing in case you haven't noticed ;) Anyway I would really appreciate some help here since I have a small baby and she sleeps a lot so I can't disturb her with the sound coming from the speakers. I have a Toshiba Satellite P200-1IE and Ubunto 12.10. Thanks in advance

Try setting the Front Headphone Jack to true with alsamixer. – Richard Ayotte Dec 29 '12 at 23:37

In this file: /usr/share/pulseaudio/alsa-mixer/paths/analog-output-headphones.conf

Comment those line as shown:
[Jack Front Headphone]
#required-any = any

[Jack Headphone]
#required-any = any

Restart PulseAudio without root: pulseaudio -k

I had the same issue (same computer / same problem). I resolved it by installing the lastest drivers from alsa-project:

wget ftp://ftp.alsa-project.org/pub/driver/alsa-driver-1.0.25.tar.bz2
tar -jxf alsa-driver-1.0.25.tar.bz2
cd alsa-driver-1.0.25/
./configure --with-cards=hda-intel --with-oss=yes
make
sudo make install

restart your computer and enjoy.
