No sound

(1/2) > >>

hi guys,

I am a newbie and recently I was troubleshooting my sound - which at the time was crackling - but now I have no sound, to which I sound card is not detected or is deleted.  Can you please help?  I tried following the sound troubleshooting in the manual options for my OS and this is what I got up to.

I really can't stand no sound - no music, no videos, mo' problems.  Anywho, so I have browsed a lot of different areas and I have no access capabilities which may be the problem? In the sound control panel I have no output or no sound cards to configure.

It seems to me the system is recognizing drivers and all that and when looking I'm not I have the right compatitibility either:

The first link shows the troubleshooting I have done in terminal (sorry if it's a bit excessive):


I have attached files for any hopefully helpful information.

I need you to upload full contents of two files, both the file:


Now I ask you, have you edited /etc/modprobe.d/alsa-base.conf before issues began?

Just FYI, the system report attached isnt complete. If you can attach a full report that'd be good.

In all honesty I can't remember whether I modified the files, but I do know what during my troubleshooting I entered a command to 'kill' or 'killall' something?



I'll regenerate the system report to make solving this problem easier.

System report: https://gist.github.com/anonymous/9002858

The contents of the file alsa-base.conf.save

--- Code: ---options snd-hda-intel model=dell-headset-multi
sudo alsa force-reload
sudo gedit /etc/modprobe.d/alsa-base
options snd-hda-intel dell-headset-multi
killall pulseaudio

sudo alsa force-reload

pulseaudio -D

--- End code ---

Is made up of items you do not need, most likely saved from using some text editor, (the .save part)
(it's also an exact duplicate of alsa-base.conf )
Let us remove this file entirely typing this into a terminal:

--- Code: ---sudo rm /etc/modprobe.d/alsa-base.conf.save
--- End code ---

Now proceed to attempt loading the module:

--- Code: ---sudo modprobe snd_hda_intel
--- End code ---

Please report back on success or failure, and we can try a few other steps if need be. You may need to reboot to make reloading things easier.

Folks, please don't attach photos. Use an external website or we will run out of disk space in time. I recommend www.imgur.com Thank you :)
