Lame should not be responsible for the missing /dev/dsp. It is likely that
something else got updated as well (what else is in the yum.log?), or that
something crashed (pulseaudio, alsa, the kernel... :-) ).

The simplest way is to try to logout and login, and see if that helps. If not,
reboot. If not, reboot to an older kernel. If not, read logs for pulseaudio

Btw, I am writing off the top of my head here, but I think that mplayer should
not even try to use /dev/dsp. Try it with

mplayer -ao pulse file.wav

That should force mplayer to use pulseaudio (which should be the default by
now, IIRC). If necessary, put it in mplayer's config file.

HTH, :-)
