No sound

No sound =<

I'm running Ubuntu 8.10

[Inkster]

what sound card are you using?

[Znurre]

Install openal.

Please don't use Ubuntu's OpenAL package if you want good sound. It is quite bad.

Open up a terminal, then type:

sudo su

And enter your password, and then:

apt-get remove libopenal0a
apt-get install build-essential libasound2-dev cmake wget tar bzip2
exit

wget http://kcat.strangesoft.net/openal-releases/openal-soft-1.5.304.tar.bz2
tar -jxvf openal-soft-1.5.304.tar.bz2 && cd openal-soft-1.5.304
cmake . && make && sudo make install

Also if you are on the vanilla GNOME version of Ubuntu, you likely won't be able to get sound in any configuration, because they use PulseAudio instead of ALSA now, in a permanent way.

I say permanent because they made GNOME depend on it, thus it cannot be removed.

You will need to wait until either OpenAL Soft or NGD officially supports PulseAudio.
(Although some people have had some luck with it's ESD emulation...)

I'll try that out later tonight. I'm on my old machine right now.

Oh, and thank you for the help.

I got it to work. I just changed the sound setting's around.

i dont have any sound i tried to enter the su command but it says that authentication fails and i have tried all the different configurations for both of the sound cards i have in the computer i am running ubuntu 8.10 with a c-media surrround card by A Open

It's easy to fix it on Debian:

Add this line to your /etc/apt/sources.list:

deb %%% experimental main

where %%% is the normal URL for the debian mirror you use.

Then run as root: apt-get install libopenal1/experimental

Afterwards, remove or comment out the experimental line you added. This fix may also work on Ubuntu, or it may break it.

What's the difference between the openal in experimental compared to lenny?

I use the lenny one now (1:0.0.8-8) and the etch before that, and I've never had a problem with it, is the experimental version significantly newer?

You can also try sudo su or sudo sh to enter a root shell with your own password.

The OpenAL libraries provided by distributions (libopenal, as it is so called) isn't an actual library, it's more like an example. That's why Creative calls it the SI ("Sample Implementation"). This means that how good it works varies greatly depending on your hardware and system configuration.

The new experimental package is none other than OpenAL Soft:

OpenAL, the Open Audio Library, is a joint effort to create an open, vendor-neutral, cross-platform API for interactive, primarily spatialized audio. OpenAL's primary audience are application developers and desktop users that rely on portable standards like OpenGL, for games and other multimedia applications.

This library is meant as a compatible update/replacement to the OpenAL Sample Implementation (the SI). The SI has been unmaintained for quite a while, and would require a lot of work to clean up. This is a fork the old Windows version to attempt an accelerated ALSA version of an OpenAL implementation.

OpenAL Soft supports mono, stereo, 4-channel, 5.1, 6.1, and 7.1 output, as opposed to the SI's 4-channel max (though it did have some provisions for 6 channel, this was not 5.1, and was seemingly a "late" addition). OpenAL Soft does not support the Vorbis and MP3 extensions, however those were considered deprecated even in the SI. It does, though, support some of the newer extensions like AL_EXT_FLOAT32 and AL_EXT_MCFORMATS for multi-channel and floating-point formats, as well as ALC_EXT_EFX for environmental audio effects, and others.

OpenAL Soft is a true reference implementation that supports the OpenAL 3D sound API "to a T". Furthermore, because it uses software mixing, it guarantees that all users will be hearing the exact same thing, regardless of how poor or awesome their hardware is.
