How to change default notification sound on Skype

The only way to change notification sound and/or volume is by manual change/edit the m4a file into APK.
Steps:
1. google how to download skype_ver_x.xx.x.apk file
2. google how to explode .apk file (sry can't insert link cause this forum weird rules)
3. the file you must change is into skype\res\raw\skype_notification.m4a.
3.1 download the .mp3, .wav, .any sound format you like as notification for your skype
3.2 optional but i suggest you to use a sound editor to increase the volume of that...
