Hi all!

I have some problems with sound on Gentoo system.

When i try play mp3 track, i get message:

From Totem:
You do not have a decoder installed to handle this file. You might need to install the necessary plugins.

From RhythmBox:
Unable to activate plugin Cover art

From madplay:
audio: /dev/dsp: No such file or directory

When I tested the sound, through the Settings->Sound, the sound is avaliable...


alsa-utils was configured and mixer works

How do I fix these mistakes?

Ok, it's not your sound system that's the problem, it is configured correctly. You need to install a codec to play mp3 files. I don't know how to do that in Gentoo, sorry!

Look at this link: http://gentoo-wiki.com/HOWTO_Emerge_MPlayer, Might help you....

what software do you want to use to play your mp3 files? I'll help you set it up, and anything else you need help with for gentoo.

to get the ball rolling please post your /etc/make.conf file

When I try to play mp3 through mplayer, it is produced. To play mp3 files I use RhytmhBox. But now is not working, no program except for mplayer.

My make.conf file:

# These settings were set by the catalyst build script that automatically
# built this stage.
# Please consult /etc/make.conf.example for a more detailed example.
CFLAGS="-O2 -mtune=i686 -pipe"
CXXFLAGS="-O2 -mtune=i686 -pipe"
# WARNING: Changing your CHOST is not something that should be done lightly.
# Please consult http://www.gentoo.org/doc/en/change-chost.xml before changing.
CHOST="i686-pc-linux-gnu"
