No Sound in Ubuntu 10.04 on my netbook apart from headphone jack
 

Hi,
I am very new to Linux of any description.
I have installed Ubuntu 10.04 and it all works apart from the sound, which only works through the headphone jack.
I have checked all the boxes and settings , nothing is muted or turned off, re-installed pulseaudio and now i am at the end of my patience.
I have read others comments on how to fix it, but to be honest I didnt have a clue what they were talking about , something about changing values or something, I wouldnt know where to start!
Can anyone please help before I go out and buy Windows 7??

Many thanks

Martin

/etc/modprobe.d/alsa-base
 

where is this text and how do I add to it????

how to add options to file alsa-base.conf
 

options snd-hda-intel model=ref


I have just installed Ubuntu on my netbook and it has no sound now, ive looked at several 'fixes' , one says to addthe above to another line?

This makes no sense to me, where do I add it to? I need to add:

options snd-hda-intel model=ref

To:
/etc/modprobe.d/alsa-base.conf

where do i do this and how?

thanks
Martin

/etc/modprobe.d/alsa-base.conf is the name of a file. Try to open it with a text editor. You can find it in the directory "modprobe.d" under the directory "etc" under the root directory.

If it doesn't exist, you can create it, and add that line to it in one simple step.

open a "terminal" aka "command prompt"
(looks like a window with white letters on black background, somethimes black letters on white, or green on black)

there execute the following command:

PLEASE stop posting what is basically the same Q all over LQ, sit back, and give someone a chance to answer you.

/etc/modprobe.d/alsa-base is a file (except that it is called /etc/modprobe.d/alsa-base.conf ) on my ubuntu 10.04

Meanwhile, we need to know more about what your sound card is.
lspci in a terminal is likely to tell you, then you tell us.

Have you run alsamixer in a terminal, and turned everything up?

Welcome to LQ.

If you gave us a link to these "comments", and just what you do not understand, perhaps we could help you better ;)

OK.
I have read all your posts about this problem.

It seem that to get sound working you'll have to:

Open a terminal
Type sudo nano /etc/modprobe.d/alsa-base.conf
Give your password.
Enter the following text as new line in the file:
options snd-hda-intel model=ref
Save the changes and exit:
Ctrl-o Return Ctrl-x
Reboot.
Any better?

If not, please answer the questions in the above posts.

I have asked the mods to place all your posts on one place, here.

still lost!
 

I have opened the file in the terminal window, lots of info there, where do i enter the new line? I appreciate your help

Enter the new line, anywhere, I don't think it matters, but it must be on a line of its own, not added to any other line. Be very careful not to change anything else in the file, just add the extra line.
Blank (empty) lines in the file do not matter, and will be ignored.

The cursor arrows, Home, End and Return keys will help you here.
nano is just a very simple editor. It's pretty intuitive (and smart, when you get to know it a bit better).

From your lspci output, your sound is:
