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
