I just installed Ubuntu 10.04 and I have no sound.
I have checked and headphones do work(BARELY AUDIBLE), however the laptop speakers do not.


Thanks, Aoude

What have you tried to do to fix it? Do you notice the Sound icon? Left click it. Do you see the word Mute? Or do you see Unmute. If you see Unmute, then click it.

Also, on the System>Preferences menu you will see an entry called Sound. Select it. On the dialog box and on some of the tabs you will see a tick box labeled Mute. Make sure that none of them are ticked. You can also adjust the Output volume. Make sure that it is not set to the lower end of the scale.

Regards.

All of the general help, alsamixer, saving sound settings, and adding the current user to the audio group(audio:x:29:pulse:patrick).

I previously used ubuntu 8.04 and it was lovely. Finally , now i installed 10.10 but now sound doesn't work at all.

i hv checked the 'use sound devices' in the 'users and groups' window but that doesn't solve the issue.

I'm new to this and doesn't know much of ubuntu. so please detail the solution.

hmm, try following the guide I posted and if that doesn't work for you we may be stuck in the same boat :(

Similar to you I had 10.10 and I downgraded to 10.04 due to an issue, now I have no sound (note this was a clean format install). However sound did work fine on the Live CD of 10.04

There's a great audio troubleshooting page here: https://help.ubuntu.com/community/SoundTroubleshooting

Worked great for me when my sound wasn't working.

The sound from my sound-card went quiet about 2 weeks ago. I have not found a solution yet, but it may be to do with this (https://bugs.launchpad.net/ubuntu/+bug/708586).
