I spent some time looking through the documentation on www.lunarlinux.org
and teh forums there.
This distro is quite different to anything I have used before. There are some tings I think you will need to look into.
I know you installed Alsa, did you install as well 'alsa-utils' and 'alsa-lib' packages? If not, you will need them to get alsa going.
I'm wondering if you would find better help on their web site? Just a thought... This distro is not what I would call 'main stream', not that I think that is bad, just things are installed differently, and that can lead to problems people without the experience in lunar linux may not understand immediately.
Is this your first leap into linux? If yes, you might be advised to pick an easier distro to install and configure. I would consider FC, Mandriva, or one of the flavours of Ubuntu easier. Once again, just a thought.
