Slackware 14.0:No sound


Hi guys,

I done a clean install of Slackware 14 in my desktop and i have a problem with my onboard audio card.
Motherboard : Asus p5k
Audio card model : Realtek ALC 883, 8 -Channel High-Definition Audio CODEC

when i try to play from some kind of media player, e.g dragon,audacious xmms , complaint about : Couldn't open audio, Please check that : Your soundcard is configured properly mpla mpla mpla......
The problem is , that i don;t have any other process that use audio resources....(except if my ears have problem.... )
This was not reproducible when i first boot.
I think, that the error initialized when tried to play a mp4 video that should had audio but unfortunately , Mplayer or Kplayer or Dragon failed to play audio.
From that moment , no audio with every media player in my desktop.

Here are some useful information :

Code:

I tried this solution but not helped.

Suggestions for how to fix this would be appreciated.

Is this just in KDE or in a console (not a Konsole)? Check to make sure your user is in the audio group (and probably plugdev too, I don't remember for sure).

[Solved]Slackware 14.0:No sound

Marnold

you were right.
Somehow the user removed from groups - I add again in audio and plugdev. Reboot and voila....my old 4.1 speaker have life again.
In the dialog ,of inserting new user i remember that i had press up key in order to add the user in the default groups - I had sound when i first boot.
Mystery is how user removed from the groups????Any idea???


Note.In the meantime , between good and bad audio state i create the vboxuser groups and using usermod add user....

can it be you used usermod with the -G option? From "man usermod"
Code:
-G, --groups GROUP1[,GROUP2,...[,GROUPN]]]
           A list of supplementary groups which the user is also a member of. Each group is separated from the next by a comma, with no intervening whitespace. The groups are subject
           to the same restrictions as the group given with the -g option.

           If the user is currently a member of a group which is not listed, the user will be removed from the group. This behaviour can be changed via the -a option, which appends the
           user to the current supplementary group list.
as an habit, if I have to add an user to an additional group I use gpasswd
Code:
gpasswd -a myuser mygroup
