FMOD_OS_File_Open : fopen failed to open 'RIFFئf', errno = 44

Hi FMOD community,

For the unity webgl build I am getting above error.

I am using player instrument to play dialogues, this works fine in editor, but it’s throwing following errors in webgl build
[FMOD] FMOD_OS_File_Open : fopen failed to open ‘RIFFئf’, errno = 44
[FMOD] System::createSound(RIFFئf, 128, 0xa5deb8, 0xa5dea8) returned ERR_FILE_NOTFOUND for SYSTEM (0x4D43920).
[FMOD] EventInstance::createProgrammerSoundImpl : Programmer sound callback for instrument ‘0’ returned no sound.

PFA code for the same.
Any help is appreciated.

        internal void PlayVoiceAudioClip(string key, Action _callback)
        {
            if(_voiceEventReference.IsNull){ return;}

            GCHandle stringHandle = GCHandle.Alloc(key, GCHandleType.Pinned);
            _voiceEventInstance.setUserData(GCHandle.ToIntPtr(stringHandle));
            _voiceEventInstance.setCallback(_voiceCallback);
