Use each music and each audio format with each size as Ringtone , Alert , Alarm
I finally found : Use .m4a , .wma , .wav and .mp3 formats as Alarm,Alert,Ringtone ((without size and length limitations))
without changing the audio name for example Alert-01.wma or .....
first copy/paste your favorite(s) music(s) to \windows
ok go [HKCU/ControlPanel/Sounds/
OEMNotifications << for Alerts
OEMAlarms << for Alarms
OEMRingtones] << for ringtones < as Alarms
in these 3 folders add "new value" and then :
: name.m4a or name.mp3 or name.wav or name.wma << name=name of your audio file that pasted in WINDOWS folder.
: enter a name for your audio that you want to be shown.
then click "ok
" to set it and go to Setting>ringtones+sounds and see
I tested with .aac , .amr , .m4a , .ac3 , .aiff , .flac , .mka , .mp2 and .ogg formats but just .m4a
worked as SMS Alert.
I try it to add a small .mp4 video as ringtone but did not work.
I think if we can add more formats for Ringtones Category it will be possible to have video as ringtone.
(important) If you use a long music as sms alert for example you can not stop playing it so you must shutdown your phone.
I think with this registry tweak all applications related to Ringtones and RingtoneMaker and ... must be change.
