AudioSource looping

I don’t really use this class, but noticed the other day that this fails:

AudioTransportSource transportSource;



Guessing an override in the transport class got lost somewhere along the way.

It depends if there’s a source:

bool AudioTransportSource::isLooping() const
    const ScopedLock sl (callbackLock);

    return positionableSource != nullptr
            && positionableSource->isLooping();

No source, no looping available.
