If you run PA in system mode, than it will drop privs and becomes a
normal process as user "pulse". You thus have to give access to the
audio devices to that user, no 666 necessary.

  setfacl -m u:pulse:rwX /dev/snd/*

Please file a bug to upstream ALSA asking that they return EPERM or
EACCES on an access failure instead of the misleading EINVAL they are
apparently returning.
