Bug 33731: Allow for default sounds on SCO page

Bug 33731: Allow for default sounds on SCO page

To test:
1. APPLY PATCH
2. Enable AudioAlerts system preferencce
3. Set up some audio alerts to trigger on the SCO page. ( I used #sco_main for east testing)
4. Make sure the sounds work properly.

Note: It is not my favorite thing to duplicate these assets for intranet and OPAC, is there a better way?
