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-module-gconf-0.9.21-13.el6.i686 pulseaudio-module-x11-0.9.21-13.el6.i686 pulseaudio-gdm-hooks-0.9.21-13.el6.i686 pulseaudio-libs-glib2-0.9.21-13.el6.i686

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

lame-3.99.4-2.el6.rf.i686 is RepoForge package, and if he is the culprit, you have to take it on their mailing list.
To test, run "yum downgrade lame", log out or better yet reboot (to be safe it is unloaded), and see if that helps.

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 etc.
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, :-) Marko

totem works great after lame downgrade. Thanks for the clue guys.

Those cards can be nothing but problems. Some say that there are common in linux but I say nothing but common trouble.
When did you update the the kernel last? Something good is `alsa-info` and read the instructions on the terminal and where to run it and get the standard output of it. You could try a diffeernt "codec" besides "lame" like mpg123. Does asound.conf point to the pulses conf file?
It is a normal thing that pulseaudio will pop and skip and snap crackle when it does not have enough of a Buffer or Priority and when a card is going bad.
Since in the above mplayer can not access pulse last thing you could do is reinstall all the pulse packages.

I downgraded lame back to the previous package and rebooted the machine. That fixed the skipping and dropouts from totem/gstreamer.
Shortly after that I got a kernel upgrade notice on my auto update tool. I installed that but declined the upgrade to lame. After reboot that still worked. Last night I reinstalled the lame upgrade and did another cold start. Still no skipping and dropouts from totem/gstreamer.

So what does 'mplayer -v 3 my.mp3' say to you?
Did you look at the Mplayer Preferences to see what the output driver is? "Alsa" Channels by Default?
Have you tried 'rpm -e nodepps mplayer'? Then 'rpm -Uvh mplayer'. If you 'yum remove mplayer' you will remove the whole lock stock and barrel. So get the mplayer rpm from the repo you use first then do it.
padsp mplayer my.mp3 works.

You want find one either. It's called 'padsp'.
I'm using pulesaudio
restart it?
Is it running as a user daemon or system daemon? what is the system load while trying to play a file?
What is the last mod time on '/etc/pulse/daemon.conf'?
lspci|grep audio lsmod|grep snd
when did the padsp-bluetooth get installed? What is the mplayer output driver? for totem i find it utterly useless.

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