I lost all sound after changing from Windows XP to Ubuntu. I installed it (ubuntu) again but no luck. Can anyone please help.

Hello,

Can you give us some specs of your computer? What is it, desktop or laptop? What brand? What steps did you take in order to fix it? What sound card do you have installed? These are some of the things that you need to include in your post when creating a new thread to help us out to help you. Please run the following commands, and post the output on here, using code tags:
Cheers,

First see if sound isn't muted.
Open a terminal and type
See if all channels are set to maximum, and aren't muted.
Use the arrow keys to navigate, up-down for the volume.
To mute/unmute a channel, press "m"

Kind regards

Hi Repo,

I don't think the sound is muted as I checked the sound system references.

Thanks.

geddo



but her is a screen shot of the sound system. sorry I couldn't past the shot.

Did you run alsamixer?

Kind regards

Hi Repo,

Yes I do run alsamixer. Thanks.

Regards

geddo

Do you have sound when you use a headphone?
BTW, in alsamixer the "M" at the bottom of the channel means muted,
"00" means not muted.

Kind regards

Hi Repo,

Yes I have sound when using the head phone. I am eager to know what that means?
