Default Sound drop out with totem. mplayer Can't open audio device /dev/dsp

Hey all.

This morning I found that my audio playback is randomly sprinkled with
sound skips and dropouts. I went to /var/log/yum.log and found this:

Feb 09 20:18:22 Updated: lame-3.99.4-2.el6.rf.i686

I'm not saying that caused the problem but it's all I could find that
changed.

When I ls in /dev there is no dsp entry.
That would explain why mplayer Can't open audio device /dev/dsp.
I don't know why there is no /dev/dsp.
MPlayer 1.0rc4-4.4.6

aplay just makes a nasty hiss.
aplay: version 1.0.21

I'm using pulesaudio

$ rpm -qa | grep pulseaudio
alsa-plugins-pulseaudio-1.0.21-3.el6.i686
pulseaudio-module-bluetooth-0.9.21-13.el6.i686
pulseaudio-0.9.21-13.el6.i686
pulseaudio-libs-0.9.21-13.el6.i686
pulseaudio-utils-0.9.21-13.el6.i686

pulseaudio-gdm-hooks-0.9.21-13.el6.i686
pulseaudio-libs-glib2-0.9.21-13.el6.i686

$ uname -a

Any of these may, or may not, be related.

seems you're mixing repos here, that's not the mplayer provided by
repoforge AFAIK.
this could be part or all of your problem.
