no sound
Hi all, I am trying to configure my card with alsa (on slackware 10.2).
I never get to see alsamixer and I have no sound at all.
I'm hoping that someone can tell me what the problem is and what to do.
Thanks.

Did you run alsaconf before running alsamixer?

You might need to install alsa-utils first. If you're using slapt-get, try <code>slapt-get --search alsa | grep yes</code> to see what you have installed. for some reason, the default Slack 10.2 didn't have ALSA-utils installed for me, either.
Alsa-utils contains alsamixer and alsactl programs.

thanks
I did a chmod on /dev/dsp and now I see alsamixer.
BUT: PCM is muted and I cannot toggle it ('m' does not work)
so I tried gnome-volume-control but same problem there, I cannot remove the red crosses (tried as root as well as user)
I am not getting an error but it just doesn't react
