[SOLVED] ALSA trivial

Hi,

Hre is my problem :

[agrum@io ~]$ alsamixer 
cannot open mixer: No such file or directory

I have installed alsa-lib + alsa-utils
I ran alsaconf and it exits well
I can start alsa

[agrum@io ~]$ sudo /etc/rc.d/alsa restart
:: Saving ALSA Levels                                                [DONE] 
:: Restoring ALSA Levels                                            [DONE]

I can't find anyone who has the same problem.
^> I found someone finally : http://bbs.archlinux.org/viewtopic.php?pid=743934
He had exactly the same problem.
So, it looks like a /etc/group entry problem.

Usually, in my case, alsa can't start or the sound card is not found, but for me everything is ok. When i start alsa, I have this annoying beep when i suppr too many characters in xterm but if I run a movie with VLC, I only get images without sounds.

I hope you can help and if you need more info ask them.
Thx.

SOLVED :
sudo gpasswd -a <nickname> audio

New problem :
I finished the ALSA wiki and when i play the wave track, no sound came from my speakers. Same problem with movies and any other stuff which improve sound. But VLC didn't write error about ALSA or sound card.

I did that also :

[agrum@io ~]$ amixer set Master 90% unmute
Simple mixer control 'Master',0
  Capabilities: pvolume pvolume-joined pswitch pswitch-joined penum
  Playback channels: Mono
  Limits: Playback 0 - 64
  Mono: Playback 58 [91%] [-4.50dB] [on]
[agrum@io ~]$ amixer set PCM 85% unmute
Simple mixer control 'PCM',0
  Capabilities: pvolume penum
  Playback channels: Front Left - Front Right
  Limits: Playback 0 - 255
  Mono:
  Front Left: Playback 217 [85%] [-7.60dB]
  Front Right: Playback 217 [85%] [-7.60dB]
[agrum@io ~]$ vlc /mnt/windows/FTP/Films/EN/A_Scanner_Darkly.avi 
VLC media player 1.0.6 Goldeneye
[0xfe2098] main libvlc: Running vlc with the default interface. Use 'cvlc' to use vlc without interface.
QPainter::begin: Paint device returned engine == 0, type: 1
[agrum@io ~]$

SOLVED :
(MM) on Speaker => going to kill my self

Thx Karol

Re: [SOLVED] ALSA trivial

I have this annoying beep when i suppr too many characters in xterm

That's a separate problem.
Try adding

setterm -blength 0    # disable console beep

to your .bashrc and

xset b off

to your .xinitrc.

If you still have problems with that damn 'beep', open another thread - there are many ways to skin this cat.

if I run a movie with VLC, I only get images without sounds

Try closing all other apps: your web browser, Skype etc. Still no sound?
