Following the PS4 Custom BGM, Theme PKGs & PS4 Background Wave FBXD Format, below is a brief guide by me (@Persona4Golden aka FLRIZBACK on Reddit) for changing the PlayStation 4 System Sounds:

1. Changing PS4 Login Sound
  • The login sound can be found in : /preinst/priv/systembgm/ and the file is called bgm_login.at9.
  • A .wav file can be easily converted via at9tool.
  • To change it, bgm_login.at9 needs to be replaced or renamed to bgm_login.at91 etc, via Full R/W FTP such as OrbisFTP.
  • Reboot.
2. Changing PS4 Background Music
  • The background music can be found in : /system_ex/app/NPXS20001/systembgm/ and the file is called bgm_main.at9.
  • A .wav file can be easily converted via at9tool.
  • To change it, bgm_main.at9 needs to be replaced or renamed to bgm_main.at91 etc, via Full R/W FTP such as OrbisFTP.
  • Reboot.
3. Changing PS4 System Sounds
  • All the files can be found in: /system_ex/vsh_asset/ and the file is called Sce.PlayStation.PUI.rco (previously named Sce.PlayStation.HighLevel.UI2.rco, not sure at what point a new firmware changed that).
  • The .rco can be easily extracted via cxml-decompiler.
  • The files converted will be in a .vag format. Most of them are 0:01 or 0:02 seconds in time, in .vag 4-bit ADPRCM 438kps at 48kHz stereo files.
  • A .wav file can be easily converted via MFAudiov11.
  • The system sounds are named randomly in numbers and letters, however a description of each file is included in the decompiled .xml file (Original and Decompiled Files by Lotus78).
Example of some file names:
  • 56EE0770.vag - default homescreen sound
  • 74C05F5C.vag - back menu sound
  • 15AA1C1E.vag - pop-up/prompt sound positive
  • 69F5140F.vag - notification sound
  • AA49BE90.vag - trophy sound
  • 11D917FE.vag - navigation back game
  • 6F9CDE26.vag - logout sound
  • BE5AD806.vag - login sound
  • 5320D326.vag - pop-up/prompt negative sound
  • B69D1B60.vag - back menu from game sound
  • 21FFB5A9.vag- boot game sound
    • Unfortunately here is where the progress ends, next and last step would be recompiling the .RCO file and replacing it via Full R/W FTP such as OrbisFTP, however no such program/script exists as of now.
  • Reboot.

@surlary and those of them who wants to play around with the files, here are original and also the decompiled files.
  • as I'm still on 5.05 the RCO file is called Sce.PlayStation.HighLevel.UI2.rco
  • the VAG files are automatically converted to WAV (so you have both Versions)
  • the exactly description which sound file is for what operation is explained in the Sce.PlayStation.HighLevel.UI2.xml (the sound files are named "src1.vag" and so on...)
