Can someone tell me why my sound stopped working?

BigOil · 04-02-2008, 10:43 PM

using 7.10 Gusty Gibbon

Sound stopped working one day.

Read many posts here, downloaded various mixer utilities and I am sure all the volumes are up and not on mute.

Interesting, if I boot from the Linux DVD the sound works, so a guy at my office said it most likely is a volume setting that's off. How can a find out what to do?

Thanks

use dmesg | less and
lspci | less

on the live version and your installed version to confirm that you're installed version found the correct soundcard hardware.

It could be an renegade driver got installed and is blocking the original Ubuntu driver.

It could be that another program is hogging the sound card.

Try running mplayer ( or xine, or whatever) from a terminal window so you can see any errors that occur.

So I did as requested and here are the results above. The crazy thing is that when I got back to the live version of Kubuntu to do this last set of commands, THE SOUND WORKED! What the heck is going on?

Since I am new to this can someone please tell me what I should look for in the above set of characters if the sound stops working again?

Thanks.

Okay, I rebooted the system and the sound stopped working again. Here are the results from those commands again:

Shows me you have a nice vanilla Audio Card which means it shouldn't be an oddball driver problem.

Have your tried this from the ubuntu community form?

Okay, problem solved. http://ubuntuforums.org/showthread.php?t=205449 helped me solve it with the uninstall and reinstall of the alsa packages (or what ever you call them).

Thanks a bunch.

I'm quickly learning that even though Kubuntu is a pretty slick looking Linux OS, it is SO NOT READY for prime time with the masses who aren't willing to troubleshoot extensively to simple stuff like getting the sound working.

Nightcrawlers · 05-17-2008, 02:42 PM

I am dual booting a new install of Kubuntu 8.04; from the first reboot after install, I had no sound. In XP my sound works fine (Soundblaster Audigy ZS) but in Kubuntu no joy.

I have tried other versions of Kubuntu and never had a sound problem ever. The only difference now is that I am running an AMD 64 3800+ cpu, and although the m/b has onboard sound, I am using the soundblaster card. I must note here that I am also running an PNY Nvidia 9600 Gt and it shows up in sounds as a sound card(?); I manually choose the Audigy but still no sound.

Also, when I open Amarok I get an error "Xine was unable to initialize any sound drivers". Help me out here, I am stumped. Thanks!
