Superpowered SDK iOS - Migration from 2.2 -> 2.5 breaking changes - audio

Question

I tried upgrading the Superpowered SDK to 2.5 which had some API changes, and now the audio stopped working. I have very limited knowledge in this language.
This is how the initializer looked before:
Superpowered::Initialize(
licenseKey,
false, // enableAudioAnalysis (using SuperpoweredAnalyzer, SuperpoweredLiveAnalyzer, SuperpoweredWaveform or SuperpoweredBandpassFilterbank)
false, // enableFFTAndFrequencyDomain (using SuperpoweredFrequencyDomain, SuperpoweredFFTComplex, SuperpoweredFFTReal or SuperpoweredPolarFFT)
false, // enableAudioTimeStretching (using SuperpoweredTimeStretching)
true, // enableAudioEffects (using any SuperpoweredFX class)
true, // enableAudioPlayerAndDecoder (using SuperpoweredAdvancedAudioPlayer or SuperpoweredDecoder)
false, // enableCryptographics (using Superpowered::RSAPublicKey, Superpowered::RSAPrivateKey, Superpowered::hasher or Superpowered::AES)
false // enableNetworking (using Superpowered::httpRequest)
);
The new initializer only takes the key, I assume everything else is enabled by default?
Superpowered::Initialize(licenseKey);
The audioProcessing callback changed from
static bool audioProcessing(void *clientdata,
float **inputBuffers,
unsigned int inputChannels,
float **outputBuffers,
unsigned int outputChannels,
unsigned int numberOfFrames,
unsigned int samplerate,
uint64_t hostTime)
To the new version:
static bool audioProcessing(void *clientdata,
float *inputBuffer,
float *outputBuffer,
unsigned int numberOfFrames,
unsigned int samplerate,
uint64_t hostTime)
Previously we passed this as
return [self audioProcessing:outputBuffers[0] right:outputBuffers[1] numFrames:numberOfFrames samplerate:samplerate];
To this function:
- (bool)audioProcessing:(float *)leftOutput
right:(float *)rightOutput
numFrames:(unsigned int)numberOfFrames
samplerate:(unsigned int)samplerate
{
size_t bufferSize = numberOfFrames * 2;
float outputBuffer[bufferSize];
memset(outputBuffer, 0, sizeof(float) * bufferSize);
bool silence = true;
NSArray *players = self.audioPlayerMap.allValues;
for (SPAudioPlayer *player in players)
{
silence &= ![player processStereo:outputBuffer
mix:true
numberOfFrames:numberOfFrames
sampleRate:samplerate];
}
limiter->samplerate = samplerate;
silence &= !limiter->process(outputBuffer, outputBuffer, numberOfFrames);
if (!silence) Superpowered::DeInterleave(outputBuffer, leftOutput, rightOutput, numberOfFrames);
return !silence;
}
But that doesn't work anymore, I've tried to just change how we call it in the audioProcessing callback but it sounds like crap:
return [self audioProcessing:&outputBuffer[0] right:&outputBuffer[1] numFrames:numberOfFrames samplerate:samplerate];
The documentation isn't really helpful, it just mentions that all other properties in the initializer was removed and that all audio is now interleaved
