I tried to type the following command as you suggested but here what

sudo padsp rplayd -d

rplayd: running as group audio (29)
rplayd: running as user nobody (65534)
rplayd: adding helper for "\.mp[1-3]$"
rplayd: adding helper for "\.ogg$"
rplayd: creating cache directory `/tmp/.rplay-cache'
No protocol specified
xcb_connection_has_error() returned true

W:[pulseaudio] daemon-conf.c: Failed to open configuration file:
 Permission denied
rplayd: received SIGCHLD signal
rplayd: rplay_audio_init: cannot open /dev/dsp
rplayd: audio disabled

It seems that I should change permissions somewhere.
