No sound in linux?


I've been using linux since the beginning of the year and have had constant problems with no sound. Being new to this, I have searched the internet and many others asking the same question, but I'm not reading any solutions. Some have posted "coded" terminal replies, but that's all greek to me. I have installed an alsa package that worked for a few days and then it stopped. How do I get it to work? ps: I know where the terminal is and in theory what it does, but I don't understand code to make it do things.

Welcome to LQ!

Usually people need not look beyond selecting the correct output device and adjusting the mixer for volume.
All this is done from GUI.

Post output of

#lspci -v

Then, ask politely for explanations instead of ignoring replies where the solution might lie.

This means your hardware is supported, since at some point it worked. First thing you should do is to check the mixer application in whatever desktop you use. The problem could be a zeroed or muted pcm or master channel.

A good way to know if your system already knows about (m)any sound card is this:

Code:
# cat /proc/asound/cards 
 0 [SB             ]: HDA-Intel - HDA ATI SB
                      HDA ATI SB at 0xfe7f4000 irq 16
 1 [HDMI           ]: HDA-Intel - HDA ATI HDMI
                      HDA ATI HDMI at 0xfe9e8000 irq 19
You only have to write the first line. "cat /proc/asound/cards", the rest is just a sample about how the output should look like. Post whatever output you can get from that command here (in case you get any output at all, if not just let us know you didn't get anything back).

no sound in linux

amani: i have tried many times to change the output options until i found one that works. My son (avide linux user) advises my not to do that, but i have and for whatever reason, sometime rarely, it will start working again. then it stops. How do i "post output of #lspci -?

The key here is that alsa worked for a few days---this means you have the right driver(s) installed.

What distro (version) of Linux are you using?

Have you looked in the GUI menus for settings relating to sound?

Since you installed alsa manually, you may need to configure it manually----Can you open "alsamixer" in a terminal?

pixellany: i am using linux mint9, lucud lynx version. we have looked at the gui settings and that does not help. I can not open alsamixer in terminal and have been told it has something to do with the intel headset i have, apparently there is very little support for it. I have been working on this for weeks and I'm getting really frustrated with the whole thing. Also, why do i have to post everything at least two times, because my message is three characters short? ... any help i can get on this would be greatly appreciated. Thanks for the Gilda Radner quote, I need to remember that right now.

There is no Linux Mint "Lucid Lynx".

There is Ubuntu 10.4 LTS "Lucid Lynx" and Linux Mint "Isadora".

Based on Ubuntu 10.04 Lucid Lynx, Linux 2.6.32, Gnome 2.30 and Xorg 7.4, Linux Mint 9 "Isadora" features a lot of improvements and the latest software from the Open Source World.
Seems strange to say both at once instead of just saying "Isadora", but maybe he just wanted to be complete. Possibly another victim of ESR's netiquette...

I mean ESR overdoes it. Calls everybody an idiot. Then people see links to his posting manual and post 500 words about simple problems and everyone comes up with 100 that are vague or confusing anyways. So you have to be called an idiot, respond by trying to be extremely clear, then have an editor go over your question with a highlighter.

This does not seem to be relevant to helping the OP...
