Need help ripping out music and sounds from an android game

[This is SG]

I'm trying to rip sounds and music tracks from the Android game, スタースマッシュ (Star Smash). I followed all the steps. Converted .acb and .awb files to hca. files using VGMToolbox, then used FastHCADecoder to convert them to .wav files. But playing them gives garbled noise instead. I don't know what else to do to fix this. Is there something wrong with my process?

EDIT: BTW I also used foobar2000 with the vgmstream plugin for the .hca files, but it plays no sound from it.
