I did that, but that non-console user still have no access to 
audio / sound device as quoted below. Anything else I should do?

//////////////////////////////////////////////////////////////
$ id | sed -e 's/[ ,]/\n/g' | egrep audio
63(audio)
$ play /usr/share/sounds/freedesktop/stereo/window-attention.oga
ALSA lib pulse.c:229:(pulse_connect) PulseAudio: Unable to connect: Connection refused

play formats: can't open output file `default': cannot open audio device
$
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\

Thanks!
