I installed Fedora 2. My sound card was detected sucessfully and I heard sound during installation. I then logged into Gnome and the sound worked fine. I then switched to KDE and tried to play sound there but nothing happened. I then switched back to Gnome and the sound was gone there too. I read that there could be a conflict between aRTS and ALSA. I used the aRTS control tool and it showed what programs like xmms were using it. I don't know what could have caused this. Please help. Below is some of my system info

cat /etc/modprobe.conf

Thanks.

check the permissions on /dev/mixer and /dev/dsp

and try turning up the volume sliders on alsamixer

I've went into Alsamixer and PCM is empty and can't turn it up
