Increasing Ringtone Preview Sound \hkey_current-users\control panel\soundcategories\Ring Highlight 'Speaker' and copy it. \hkey_current-users\control panel\soundcategories\RingPreview Paste 'Speaker' into this registry location. (make sure value data is 1) You can also edit key InitVol from default 3 to 5 for a more accurate sound level of how loud your ring will be when it actually plays. Restart the device. Now any time you preview a sound it will play via the speakers and not the ear piece.
