no audio
I installed a Ubuntu+LXDE following that guide (more or less): wiki.dennyhalim.com/ubuntu-minimal-desktop
- installed a cli ubuntu jaunty from minimal cd
- install lxde: sudo aptitude install --without-recommends lxde
- install slim: sudo aptitude install slim
Got it running. Then I installed apps (openoffice, firefox, thunderbird, kdevelop, etc.), and everything working all right.
Then I proceeded to install multimedia apps: vlc and audacious. NO AUDIO. I get video in vlc but no sound. In audacious I can start a MP3 but no sound.
alsa is installed, as well as pulse audio. I tried to install amarok to see whether it would install some audio system but no.
What should I do?

Re: no audio
Most likely the audio is muted. Debug it using alsamixer. If you have pulse as your primary output you may need "alsamixer -c 0" to see your sound card.
If you Google "alsa troubleshooting" that may help you.
On my sound card the analog audio is muted unless I mute the SPDIF outputs.

Re: no audio
Are Alsa and your cards in the kernel?

Re: no audio
I'm having a similar problem. Sound works fine on boot-up, then "auto-defaults" to mute. The first thing I do when the desktop appears is to open Volume Control and un-mute it. How can I keep it from "defaulting" to mute after I log off or shut down?Marty Jack wrote:Most likely the audio is muted. Debug it using alsamixer.
I wasn't able to find "alsamixer" in my usr/share/applications folder (Ubuntu 9.04) to "debug" anything. I'm still a newbie to Linux.
Thanks,
Robin

Re: no audio
alsamixer is a command line tool. "which alsamixer" tells you if you have it installed. It comes from the alsa-utils package.
You need to make sure you're doing "alsactl store" and "alsactl restore" on shutdown and boot. This should be done for you by the system scripts.
These questions are really better directed to the Ubuntu people, who are familiar with how they set up their bootscripts.

Re: no audio
Thanks! I'll post the question on Ubuntu forums too. I've been bragging like crazy there about how fast and simple LXDE is! Thanks again for an awesome DE.

Re: no audio
We certainly appreciate the compliment on LXDE. Good luck with getting it solved. In LXDE we do not do anything behind your back that is not visible in one of the configuration files.

deed you manage to solve that problem? I would like to know the solution as I am having the same problem.You need to make sure you're doing "alsactl store" and "alsactl restore" on shutdown and boot. This should be done for you by the system scripts.

Re: no audio
I was offered some solutions that didn't work, or caused new problems. I figure it's some li'l bug in Ubuntu 9.04 I think, one that may be solved simply by some update. I'm content to "un-mute" it for now. These things are the price one pays for insisting on the "latest and greatest" cutting edge software (Ubuntu Jaunty) instead of something thoroughly tested and thoroughly stable (like Ubuntu Hardy, LTS). It's a minor little glitch and no more trouble than emptying the trash bin was in Windows. So I basically just live with it.bricedebrignaisplage wrote: did you manage to solve that problem?
