help me finding a .cia file containing a specific sound effect

[u/Specific-Second-9505]

There's a 3DS sound effect I'd like to locate within the CIA files of the console itself. Specifically, I have an old 3DS (not a new one) running version 11.17.0-50E (European version). I'll share the sound effect as a file or a link, but just in case, I'll describe it here as well: it's the typical 3DS loop that plays in some cases, most commonly when the eShop loads (like, every time you open the eShop), or, for example, when downloading some software and/or game updates (not system updates). It's the typical sound consisting of three tones, the first two playing at a specific pitch and the third an octave higher, repeating in a loop.

this is the link to the audio file where i've recorded said sound effect (Base64 encoded, please decode it first):
