No sound is my latent problem for weeks (at ubuntu 9.10).


The driver I installed successfully (wolfgang@wolfgang-desktop:~$ aplay -l

wolfgang@wolfgang-desktop:~$) It worked once but after reboot of the os there was no sound any more.

"Sound Preferences" shows on output only "Dummy output stereo")

In the manual I was told to edit the modules to have loaded the sound at boot time: "Copy and paste this to the bottom of your /etc/modules.conf or /etc/modprobe.conf file" Well I didn`t find any of this files. So I just created them and tried to copy it into the directory "etc". But the system denied to paste to those directory. Anyway it wouldn't have worked because I guess there is some other file competent to load the sound. I'm stuck now and would like to get some info of how to get rid of all of this restrictions. For the time beiing at least. And I would need to know what file in "etc" loads the sound. For any help I'm very grateful.

Have you tried just plain "module" as a file name? (My case, I am using Ubuntu 8.10 on a 9-10yo laptop).

Thanks. I have a file named modules but I can't edit it: "You do not have the permissions necessary to save the file. Please check that you typed the location correctly and try again."

Hello,

If you need to edit that file and any other files that need root permissions when logged in as a regular user, then put sudo in front of your command. The system will ask you for your user password and then grant you access if you are in the sudoers list.

Example:
Kind regards,

Thank you! I made it - that is I could edit all that files I was to in the manual... but the sound still is dead. As I do all this experimentally probably I'm gonna install some other distribution of Linux. The new MANDRIVA 2010 seems to be fine...

Hi,
1. Are you a member of 'audio' group?
2. Strange it may sound but I have read, tried and succeded by doing "chmod -R 777 /dev/snd".
3. You may also try alsamixer and see if anything is muted.
