Check and make sure that you are in the audio group. In order to access the
sound device, you have to be in the group. Run:
gpasswd -a username audio
replacing username with any user that you want to be able to play sound. Then
logout and login, see if arts gives the same error. Otherwise it seems alsa
is working correctly.
