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
