no sound

[petervdv]

Hi all, I am trying to configure my card with alsa (on slackware 10.2).
I'm hoping that someone can tell me what the problem is and what to do.
Thanks.

How have you tried to configure your card so far? Have you tried the 'alsaconf', 'alsamixer', 'alsactl store' route yet?

As a note, open programs as your user and not root.

hi, thanks for your help
alsaconf detects the card, but I don't get to see the mixer

Now ALSA is ready to use.
 For adjustment of volumes, use your favorite mixer.

 Have a lot of fun!

peter@meadow:~$ alsamixer

Check #5 on this page: http://alsa.opensrc.org/index.php?page=TroubleShooting

You may be missing the appropriate devices in your /dev folder. Try the solution there and report back with any further problems.

Thnx man the problem was that peter couldn't access the sounddevice
So now I'm getting alsamixer but I cannot unmute PCM ('m' doesn't work)

[bryansmith]

Have you tried a different mixer like KMix (KDE) or the GNOME volume control? Do you get any errors when trying to unmute PCM?

Bryan

[petervdv]

I also tried gnome-volume-control but I am unable to toggle the red crosses from PCM.
tried as user as well as root...
No errors.
