What's the output of 

%mixer speaker

Beeps don't use pcm.

Some audio and video players modify mixer values directly to control volume, instead using alsa/oss/pulse calls. Perhaps you used one of them.

Anything weird on dmesg -a output?

As a workaround, if you are using xterm under X, Ctrl+MIddle Mouse button shows a menu where you can enable visual beep. Other terminals could have similar mode.
