Sound problems
I just installed Linux Debian on my PC, but the sound isn't working. I find this rather odd, as it was just recently installed on my brother's laptop, and the sound works fine on there. To be perfectly honest, I don't have the first clue as to why the sound isn't working. I'm wondering if Linux didn't detect the drivers, if that makes any sense (still very new to Linux). I don't really know how to begin troubleshooting this problem, so if anybody could point me in the right direction, I would apprecaite it. Thanks.

Most drivers are available as module you can `plug into' the Debian stock (stock = the-one-you-get-from-debian) kernel. *) To see which modules you already have running Code:
user@localhost$ lsmod | less Code:
root@localhost# modprobe -l | less Code:
root@localhost# modprobe <NAME> *) To *always* load a module (i.e. on boot-up) add <NAME> to /etc/modules (must be root) ... play with these a little bit to get familiar with them. Quote:
if PCI (and in any case), try `lspci' and look for something that sounds like your sound card. Find the right module for your soundcard (modprobe -l | less -- search for `sound'). Is it loaded (lsmod)? --- That should go over the basic low-level stuff. How did you try to play sound? Try a few other ways. Which kernel version are you using (post $ uname --all)? Are you using OSS, ALSA, esd, artsd? Try (if you can) to make sense of /etc/libao.conf, /etc/esound/esd.conf and ~/.asoundrc Btw, read the sticky; it tells you to include `lsmod`, `uname -r` and `lspci`. Do also read http://www.catb.org/~esr/faqs/smart-questions.html (no offense meant). --- If there's anything you didn't understand, feel free to say so. hth --Jonas As an optional exercise, make your PC Speaker work if it doesn't already--I think I've given you enough hints :D |
Just a few things you can try as root:
Code:
alsaconf If this goes well, run Code:
alsamixer Then Code:
alsactl store |

Thanks for your replies everybody. Jonaskoelker, your post was very useful. However, I don't know where to input those commands.

In a terminal window. You should be able to find an entry for "Terminal" or something similar in the menu of whatever window manager you're using.
