Hello newonlinux,

there are modules (drivers) specially for various laptops in order to support the laptopspecific hardware like the functional keys or batterymanagement.

Could you please open a terminal and execute the command

Code:

lsmod | sort

and post the output here? And please post also the output of

Code:

uname -a

this laptop was bought on ebay for my parents and the username has not been changed. i don't know how to do that?? Does that make a difference? thanks for your help.

Well, I looked at the kernelsources, there seem to be no special modules for your laptop.

Otherwise all the snd_* modules are soundrelated, so the sound should work.

Please open a terminal and execute

Code:

alsamixer

you can configure the sound with alsamixer. If it doesen't work, please post a screenshot of your alsamixer-settings.

i have gone in and out and reset this sooo many times. after leaving the laptop on thru the night...there is no sound at all this morning. i checked the sound first this morning and then went into alsamixer...everything was still like it was before i went to bed, only there was no sound. thanks for your help.

mh, I'd like to look at the output of

Code:

sudo lspci | grep -i audio

I'm missing the module snd_hda_intel in your lsmod-output and I'm not sure if it would be needed.

You may execute

Code:

sudo modprobe snd_hda_intel

maybe this works.

nothing happened when i executed sudo modprobe snd_hda_intel it just went back to the $prompt. Is that ok?

Yes, then the module has been loaded.

After restarting the system, you will have to use the modprobe command again in order to load this module. Please try if this changed something with your audio.

If not, please try the command

Code:

sudo alsaconf

, this configures your soundcard (though I'd guess that with Mint this is done automatically).

If the module works, you'll need to configure your system to load this module at startup, please read the documentation.

Markus

restarted the computer; ran sudo modprobe snd_hda_intel and still had to execute alsamixer and unmute the master tab only and then i had sound; executed command sudo alsaconf and received message sudo: alsaconf: command not found.

Well, if it is working now, you'll have to configure the module snd_hda_intel to be loaded at systemstart.
Anywhere in the /etc directory, there is a file "modprobe.conf" there you'll have to add "snd_hda_intel". This will load the module automatically when the system starts.

Markus

sounds great..only I don't have a clue how to configure anything on this computer.

mh, you will need an editor, for example nano. Open a terminal, enter the /etc directory and find out if there is a file modprobe.conf.

Code:

cd /etc

ls

then you may open the file with the editor

Code:

sudo nano modprobe.conf

you add a line snd_hda_intel, save with <CTRL>+<o> and leave the editor with <CTRL><x> (as far as I know.

Markus

did that - restarted just to see if the sound work work. It did not. I still had to execute alsamixer to unmute master volume tab.

Well, but the module is loaded, again one step further ;)

I had this problem with alsamixer once, but I did not find a solution back then. I'd recommend to start a new thread for this issue. Or use the search-funktion here in the forums, maybe you'll find a solution there.

Good luck

Markus

ok thanks for your help
