Fix Sound Problem in Ubuntu 12.04

The general problem is with PulseAudio has to have some kind of support for our Intel HDMI Audio Card
To solve this: Alsamixer
Alsamixer is a graphical mixer program for advanced sound architecture for Linux (ALSA). Used to configure the sound settings and adjust the volume. It has a user interface based on ncurses and does not require the X Window System. It supports multiple soundcards with multiple devices.
So get to work! open a terminal and continues with this:

sudo gedit /etc/modprobe.d/alsa-base.conf

Add this line to the end of file

# NEW LINE

options snd-hda-intel model = asus

Now put this in the terminal to download the ALSA packages:

wget ftp://ftp.alsa-project.org/pub/driver/alsa-driver-1.0.25.tar.bz2
wget ftp://ftp.alsa-project.org/pub/lib/alsa-lib-1.0.25.tar.bz2
wget ftp://ftp.alsa-project.org/pub/utils/alsa-utils-1.0.25.tar.bz2

Now install the following:

sudo apt-get install libncursesw5-dev build-essential libncurses-dev gettext xmlto xmltoman linux-headers-`uname -r

Now copy the system alsa:

sudo mkdir -p /usr/src/alsa
cd /usr/src/alsa
sudo nautilus

Let> / home / user / Downloads /

We copy the files: "alsa-driver-1.0.25.tar.bz2", "alsa-lib-1.0.25.tar.bz2", "alsa-utils-1.0.25.tar.bz2"

Now go to / usr / src / alsa

And paste files.

Now unpack:

sudo tar xjf alsa-driver*.bz2
sudo tar xjf alsa-lib*.tar.bz2
sudo tar xjf alsa-utils*.tar.bz2

Now let's compile and install Alsa:

sudo ./configure –with-cards=hda-intel –with-kernel=/usr/src/linux-headers-$(uname -r)
sudo make
sudo make install
cd alsa-driver*

Follow this:

sudo make
sudo make install

Finally this:

sudo ln -s libpanelw.so.5 /usr/lib/libpanelw.so
sudo ln -s libformw.so.5 /usr/lib/libformw.so
sudo ln -s libmenuw.so.5 /usr/lib/libmenuw.so
sudo ln -s libncursesw.so.5 /lib/libncursesw.so

Finally:

cd ../alsa-utils*
sudo ./configure
sudo make
sudo make install

Note: Now Reboot your Ubuntu!

Then:

Open a Terminal

Write: alsamixer

Press F6 key

Select 0 HDA Intel

The item "Capture" Get it to level 25

The item "Internal Mic Boost" take it to Nuvel 51

If pressing the arrow to the right, there will be more than the volume meters are displayed at first.

Press the Escape key

We finished!
