I discovered that the sound stops working when I replace the GDM login manager with the SLiM login manager.

>From Googling around, I found that the problem was a permissions issue.  Entering the command "sudo adduser (username) audio" restored the audio capability.

That said, this is an issue I need to resolve for users of Swift Linux.  Part of the process of transforming Linux Mint Debian Edition into Swift Linux is replacing the GDM login manager with the SLiM login manager.  How can I make the audio work out-of-the-box for Swift Linux?  Why is this an issue in SLiM but not in GDM?  (Or is this an issue in GDM that the Linux Mint developers already took care of?)
