Looks like your build is screwed in some way.

Either you have dangling root files or versions files. Try make mrproper
as root to clean the tree (after backing up your .config).

Did you try playing with a mixer like gmix ? The best way to try if
the sound driver works is the console beep. There are plenty of
reasons why a userland app would fail emitting sound, but the
console beep is entirely kernel driven.
