Well, I searched for my sound card and it is in this file:


If it was me, I would rename the file, maybe add .old on the end, then 
login and see if things work.  If not, you may want to rename the file 
and put it back.  I suspect this will fix it but I haven't tested it.  
If it breaks, you can have the pieces. No promises.

I have ran into this before but I just didn't answer yes.  I'm not sure 
why it doesn't see my card at times.  It's rare that it does this but 
you are not alone on this problem.

Hope that helps.
