Problème de son avec Mandriva LE 2005, bon aussi ProblemeDeSon2006 ...

Errors encountered with sound

• Lancement de Amarok - solved

Error while initializing the sound driver:
device /dev/dsp can't be opened (No such file or directory)
The sound server will continue, using the null output device.

• lancement de gnome-sound-control - solved

aucun éléments et/ou périphériques de mixage trouvés

The applet for sound stays at 0 even if I move it (under Gnome) - not solved (well works, did not find how...)

Some tests

• aplay english.au # with sample sound file above : it may work but you may not have sound in Amarok yet (which uses arts)
• aplay /usr/share/sounds/KDE_Startup.wav # should play boot music of KDE

• add your user to the audio group then ps auxww|grep arts and kill arts processes (they come back) this worked for me

• service alsa stop ; service alsa start # to restart alsa, just in case

gui for alsamixer

To change the volumes, use one of this program :

• gnome-volume-control
• alsamixergui

Some diags

• lspcidrake -v | fgrep AUDIO gives the sound card recognized, on an A7N8X-X :

snd-intel8x0 : nVidia Corp.|nForce2 Audio Codec Interface [MULTIMEDIA_AUDIO] (vendor:10de device:006a subv:1043 subd:8095)

• lsmod|grep snd gives the modules loaded
