There are three people with logins to my desktop box --
myself, my wife and my daughter. My daughter plays Flash
games with sound all the time and has no problems. I run
YouTube videos and otherwise use sound with no problems. My
wife gets no sound whatsoever. We used to have a problem with
the sound being grabbed by something and then I would need to
kill things manually, but I eliminated all KDE apps and that
problem went away. I think that was back when I was still
running Etch, anyway. When I need to verify that sound is
working and not locked up, I just use 'play' with a .wav file.
My wife was just playing a video and getting no sound, so,
under my login I ran:
play /home/marc/public_html/footpain/media/montoya.wav
/home/marc/public_html/footpain/media/montoya.wav:
File Size: 14.8k Bit Rate: 13.1k

Done.
and, as you can see, it worked just fine.
So I swiched over to my wife's login and did the same thing:
play /home/marc/public_html/footpain/media/montoya.wav
ALSA lib pcm_dmix.c:985:(snd_pcm_dmix_open) unable to create
IPC semaphore
play FAIL formats: can't open output file `default':
snd_pcm_open error: Permission denied
As you can see, it failed. Can anyone tell me just what is
failing and how to correct it. My first thought was that it
was a permissions problem and perhaps she needed to be added
to the 'audio' group, or some such, as she is only in her own
group. But then I checked my daughter's account. She is also
only in her own group; not in 'audio' or anything else. So
that ruled out that solution. The error says 'Permission
denied" however, so it is some kind of permissions problem, I
just don't know what.
Any help will be greatly appreciated.

You should use
ipc_key_add_uid TRUE
in your .asoundrc when defining dmix.

Is that a user lever file? I do not find that config file anywhere
on my box.
