I recently upgraded my 4500 the the latest version, 8.06.08. Somehow now I am not getting any audio alerts from the AOA. The display works correctly, but no sound. Also, I am finding after powerup that the audio setting in the AOA page is somehow being set to OFF, but even when I turn it to ON it isn't providing any sound. Am I missing something? Thanks!
