Sound permission problem

I'm running Fedora F7, without X. I'm able to do 'mplayer <url>' for
one user at a time. However, I'm not able to do 'mplayer <url>' for
one user, and then 'mplayer <another-url>' as another user. Then I get
the following error message:

[AO_ALSA] alsa-lib: pcm_dmix.c:831:(snd_pcm_dmix_open) unable to
create IPC semaphore
[AO_ALSA] Playback open error: Permission denied

It's not important to me to play mplayer that way, however, I want to
be able to run speech-dispathcer (which, BTW should have an rpm pacage
for Fedora) and play mplayer at the same time. How could I solve this
permission problem?

I've tried to put in /etc/security/console.perms.d/50-default.perms:

<console>  0666 <sound>      0600 root,

and ls -al /dev/audio gives:

crw-rw-rw-+ 1 lrs root 14, 4 2007-11-29 10:00 /dev/audio
