Wave audio plays glitchy on Emscripten SDL2 (apple silicon)

[h0111in]

hi , I couldn't figure out what makes this code play the audio glitchy (like playing 44.1k file at 48k speed)
here is the code:

    `soloud = std::make_unique<SoLoud::Soloud>();
    sharedWav = std::make_unique<SoLoud::Wav>();

    soloud->init();
    cout << sharedWav->load("assets/music_48k.wav") << endl;
    
    auto handle = soloud->play(*sharedWav);`

later I added:
soloud->setVolume(handle, 0.2f); // or whatever level soloud->setSamplerate(handle, soloud->getBackendSamplerate()); soloud->setRelativePlaySpeed(handle, 48000.0f / 44100.0f); soloud->setVisualizationEnable(handle); // optional

my build command:
