Well you could always use rpmdrake to see what you have installed. Thats probably not the best way but if you search for alsa you will be able to find the version you are using. Also you should be able to see it during boot up if you press escape during boot you will see the processes starting up.

Also check services. Go to Configure your Computer->Systems->Services and see if alsa is running.

I'm not the best at this but I hope I am helping a little

I have tried to get the sound to work from my audigy mp3+ card, but no luck. I used the ALSA to make it work, and it did. But when I try to run Realplayer, XMMS, and MPLAYER there is no sound. I have made it work before, so I sat there thinking. Playing on an old Aptiva that my parents gave me I remembered that on my Dell when I installed MDK 10 I had the onboard sound card enabled. The device "dsp" was automatically created. That seems to be the problem with the audigy card. When you try to use it it says that the kmixer can't find "dsp" from /dev folder. So I am proposing that you install you MDK 10 with your onboard sound enabled. Then when the software reads your onboard card, it will generate the "dsp" file that you need for audiogy. After you can then install the audiogy card and use the already made "dsp". If you makedev /dsp it wont' work, even if you override it using the dsp options, it will tell you that the permission is denied, and if you chmod 666 it will allow you to apply the option, but you still won't get sound.
