Thank you. ** Creating an /etc/asound.conf (to define a default sound card) and rebooting made the machine hang for such an extended period during the boot sequence that I ctrl alt del into recovery mode and deleted the newly created file. Upon rebooting once more things had returned to normal again--unless I'm nuts.
