I recently installed kubuntu with KDE 4.1 on a Aspire 6920 which is a 64 bit system with these specs

# Processor: Intel Core 2 Duo T5750 (2.0GHz, 667MHz FSB, 2MB Level 2 cache)
# Memory: 4GB 667MHz DDR2 SDRAM (PC2-5300)
# Hard drive: 250GB (5400rpm)
# Graphics: Intel X3100 integrated graphics
# Optical drive: DVD SuperMulti DL
# Ports: Ethernet, modem, VGA, microphone in, two audio out jacks, four USB ports, 5-in-1 card reader, ExpressCard slot.

I am not getting any sound in neither the KDE or the Gnome, I have tried to check the drivers, but don't really know how, I would like to try and re-install them to see if that would solve my problem, unless their is another way. I am new to Linux, and like what I see so far, but it sucks not to have any sound. If anyone has any suggestions that would be much appreciated.

This is likely because of one of the following:
A ) The sound driver requires special arguments to work with your sound card
B ) Your sound card requires the Modem to function ( its probably a Conexant )
C ) Your sound card is not supported with the revision of software in the distribution you have installed.

Could you please post the output of "lspci"

thanks for the reply
I would love to do that but, honestly I dont know how. Sorry I am really new to Linux so maybe you wouldnt mind telling me what it is i need to do to get that report.

In Konsole, type this command

Code: Select all

lspci > ~/lspci.txt

Then copy and paste the contents of ~/lspci.txt here

You don't mention a specific sound chip but, if it is an integrated Intel sound chip, in some cases, it can be turned on by opening a console and entering
su --
rcalsasound restart
after each reboot.
It may not work but, if it does, it will give you sound until the problem is fixed properly.

When I typed in Ispci into the Konsole this is what came up:

When I typed in the command as you posted, nothing happened, I tried to type in the command ~/lspci.txt but all i got as a response was access denied. I hope this can help.

~/lspci.txt is a path to a file. ~ Is a shortcut for the path to your home directory (/home/your_username), so the file is located here: /home/your_username/lspci.txt.

The line - lspci > ~/lspci.txt - bcooksley asked you to run directs the output of the command "lspci" to a file called "lspci.txt" in your home directoryl. But as it printed out the result on the commandline as well you've got everything you need, you can delete lspci.txt in your home directory as well.

No idea about the sound issue though. It could be that there are no sound drivers installed. Can you verify if packages containing the name "Alsa" are installed on your machine?

From what I can see your sound card is fairly common and should have proper support.

I tried entering the command su -- and when it asked for the password it gave me an Authentication failure, what is it that this command does? Is the password the same as the log on password or is there a way to change it so that I have a separate password for the Konsole?

su is the command to switch to the root user or administrator of the machine. When you installed the OS you're running you were asked to set a password for the root user. It's the same password you use when you install new software from Synaptic, Add/Remove Software (in Ubuntu), PacMan, YaST or whatever packagmanager you're using.

thanks, for the info that makes sense

I checked if I had Alsa
and the packages that I have installed are:
Alsaplayer
QAmix
Alsamixergui
Gnome AlsaMixer

I initially thought that it was the lack of a driver so I installed these packages, but it did not solve the problem, maybe there is one that i am missing

I also found it under the default sound card which was installed when I installed Kubuntu

Hmmm. Did you get that information from the "Add/remove programs" dialog, or is this from Synaptic? If the former applies you might want to recheck in Synaptic, there should be some libraries installed as well and that list only contains applications.

I have alsa-base, alsa-modules, alsa-source-current-kernel-version and alsa-utils installed, along with libasound2.

What is the output of these two commands?

Code: Select all

groups
ls /dev/snd/

Yeah that was from the Adept manager, I went ahead and looked in the Synaptic Package Manager and I found these programs Installed:

alsa-base, alsamixergui, alsaplayer-alsa, alsaplayer-common, alsaplayer-gtk,
alsaplayer-source, and alsa-utils

Dont know if that helps any

Alright when I typed in that command this is what came up

ls /dev/snd/
controlC0 pcmC0D0c pcmC0D0p pcmC0D4c seq timer

Try downloading a WAV file from somewhere then launch this command: aplay /path/to/downloaded/wav
