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
Encoding: GSM
Channels: 1 @ 16-bit
Samplerate: 8000Hz
Replaygain: off
Duration: 00:00:09.04
In:100% 00:00:09.04 [00:00:00.00] Out:434k [ | ] Clip:0
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.
