Ubuntu Gutsy and MCP51 (snd-hda-intel) - what to do to make it sound

It seems that not only me, but also the majority of newly installed Ubuntu Gutsy on mothers with integrated sound on the MCP51 chip (defined on most of them as snd-hda-intel) have problems with sound - the card is simply not defined.

Firstly, there are several sources that I used, but there are two main ones, the first one is Ubuntu Answers and the second one is Hda Intel Sound How to .

Secondly, everything described below looks like a huge change to the system as a whole, the kernel or the packages in particular, but believe me, this will only add new functionality, but it won't break even if you try sooo (without fanaticism, please! :).
')
Third, do not forget to turn on the sound in BIOS! I stepped on it and killed a little time, but enough :)

Now in order:
1) Add the necessary for the assembly alsa'y packages in the system:

$ sudo apt-get install build-essential ncurses-dev gettext
$ sudo apt-get install linux-headers-`uname -r`

3) Download the latest versions of the drivers , libraries and utilities from the alsa site:

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

$ wget ftp.alsa-project.org/pub/driver/alsa-driver-1.0.15rc3.tar.bz2
$ wget ftp.alsa-project.org/pub/lib/alsa-lib-1.0.15rc3.tar.bz2
$ wget ftp.alsa-project.org/pub/utils/alsa-utils-1.0.15rc1.tar.bz2

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

4) Compile and install the driver (pay attention to the key!), Libraries and utilities:

$ cd ../alsa-driver-1.0.15rc3
$ sudo ./configure --with-cards = hda-intel
$ sudo make
$ sudo make install

$ cd ../alsa-lib-1.0.15rc3
$ sudo ./configure
$ sudo make
$ sudo make install

$ cd ../alsa-utils-1.0.15rc1
$ sudo ./configure
$ sudo make
$ sudo make install

5) Reboot.

6) After a reboot, a card should appear in / proc, look at it:

$ sudo cat / proc / asound / card0 / codec # * | grep codec
Codec: Analog Devices AD1986A

7) Go to this link , look for the card and see which mode to set. In my case, this is 3stack.

8) Add one line to alsa config:

$ sudo vim /etc/modprobe.d/alsa-base

i
options snd-hda-intel position_fix = 1 model = 3stack
:
wq

9) Again we reboot.

10) Configure alsa:

$ sudo alsaconf

there must be a “card”, for example, in my case it is hda-intel

11) Check the setting:

$ sudo aplay --list-devices
**** List of PLAYBACK Hardware Devices ****
card 0: NVidia [HDA NVidia], device 0: AD198x Analog [AD198x Analog]
Subdevices: 1/1
Subdevice # 0: subdevice # 0
card 0: NVidia [HDA NVidia], device 1: AD198x Digital [AD198x Digital]
Subdevices: 1/1
Subdevice # 0: subdevice # 0

12) And finally, how to play:

$ aplay -vv ./alsa-utils-1.0.15rc1/speaker-test/samples/Noise.wav

The method described above was successfully tested on three identical machines, but on different ubuntas: Feisty, Gutsy and Edgy.
