I'm running a Slackware distro with 2.6.19 linux kernel.

This is my story: some time ago, I installed alsa from source (alsa-lib, alsa-driver, alsa-utils). I've had problems with applications trying to play sounds simultaneously, so I look for information about dmix, and found out that it is automatically enabled on the alsa version I had installed. Then I checked whether my applications used alsa, and found out that, for example, XMMS didn't use the alsa library but OSS's one, and it worked (except for the mixing problem). I configured xmms to use alsa, but if i tried to play something a window would pop up telling me to check the soundcard. I unistalled alsa (with 'make uninstall' on the three packages: driver, lib, utils) and decided to use the kernel built-in alsa support. I recompiled the kernel, built alsa as a module, built oss compatibilty modules too, and rebooted. Now, xmms with oss doesn't work anymore and the alsa library isn't even shown in the list of available plugins. If i try to play sounds with OSS, xmms seems to be working but doesn't output any sound and it says:
Code:
libasound.so.2: cannot open shared object file: No such file or directory
Also, i've read i should run alsaconf, alsamixer, etc. but i can't find them!

Can you help me please??
Thanks to anyone

All you installed was the ALSA driver. You still need the ALSA libraries and ALSA utilities (alsaconf and alsamixer).

Thanks you, sounds work again now.

Just one doubt, how do i tell applications that they must use alsa and not oss? I still have the mixing problem, and i think that the cause might be the fact that there are applications which still use oss.

For example:

Gaim: the sound section wants a command to use when gaim need to play a sound. Defauly is 'play', but it uses oss, doesn't it? When i run 'play', xmms (which uses alsa) tells me to check whether another application is blocking the device, which i think is /dev/dsp.

TeamSpeak: sound driver to use can be set to:
- default (oss /dev/dsp)
- default network (8780:L, don't know what this means)
- other (there is a text field whose value is /dev/dsp).

Thanks for your help!

Mixing works now, but only if applications use alsa.
Can you help me?

There is the command 'aplay' which plays sounds using alsa, so the problem with gaim is solved. But what driver do i have to use to play sounds with alsa??
