I have the same problem that the user in "Dummy Output in Ubuntu 14.04".

The difference is that cat /proc/asound/card0/codec* | grep Codec outputs:

cat: /proc/asound/card0/codec*: No existe el archivo o el directorio 

(It's in Spanish, it means it cannot find the file or directory)

More info:

$ sudo modprobe snd-hda-intel  
modprobe: FATAL: Module snd-hda-intel not found.

$ sudo alsa force-reload
Unloading ALSA sound driver modules: (none loaded).
Loading ALSA sound driver modules: (none to reload).

$ sudo aplay -l
aplay: device_list:268: no soundcards found... 

$ lspci | grep -i audio
00:1b.0 Audio device: Intel Corporation 7 Series/C210 Series Chipset Family 
    High Definition Audio Controller (rev 04)

$ lspci -v | grep audio
(nothing)

$ locate snd-hda-intel
(nothing)

$ lsmod | grep snd
(nothing)

First, we need to know what type of audio hardware (if any) the system detects:

lspci -v | grep audio

And

:~$ lsmod | grep snd

Please run this command and post the output. Should be something like the following:

:~$ lspci -v | grep audio
00:1f.4 Multimedia audio controller: Intel Corporation 82801BA/BAM AC'97 \
  Audio     Controller (rev 02)
:~$

And

snd_intel8x0           38153  0
snd_ac97_codec        130285  1 snd_intel8x0
ac97_bus               12730  1 snd_ac97_codec
snd_pcm               102099  2 snd_ac97_codec,snd_intel8x0
snd_page_alloc         18710  2 snd_intel8x0,snd_pcm
snd_timer              29482  1 snd_pcm
snd                    69238  4 snd_ac97_codec,snd_intel8x0,snd_timer,snd_pcm
soundcore              12680  1 snd
:~$

Additional information for troubleshooting

What is the output of the following?

:~$ locate snd-hda-intel

Several users on other posts were able to get this audio chipset working by editing /etc/modprobe.d/alsa-base.conf

nano /etc/modprobe.d/alsa-base.conf

And add the following line:

options snd-hda-intel model=generic

  • First of all, thank you for answering. I tried all the commands you posted and I got no output. I also tried adding the line in alsa-base (and rebooting) but it didn't work. – marlanbar Aug 08 '14 at 19:21
  • @marlan21 - I added an additional solution and posted it as a separate answer. Here we take the approach that some packages may be mis/unconfigured. – Crusty Barnacle Aug 08 '14 at 23:05

This worked for me on a Philips Freevent x55, although I had to use sudo gedit instead of nano.

Alternate method to fix sound (due to misconfigured/unconfigured packages after install/update/upgrade).

  • Fix packages that are not properly configured

:~$sudo dpkg --configure -a, then do a :~$sudo reboot

  • It didn't work either. Mmm I not exactly sure how this happened, I tried to update alsa installing the driver found in the realtek website. Perhaps it's better to reinstall Ubuntu from scratch don't you think? – marlanbar Aug 08 '14 at 23:53
  • @marlan21, maybe that is the easiest option. But, why are you installing realtek drivers for an Intel chipset? – Crusty Barnacle Aug 09 '14 at 00:01
  • I wanted to split the sound of the front connectors with the ones in the back. I read in a website that this was the way to do it, but I guess it was wrong. – marlanbar Aug 09 '14 at 00:37
