With this change, the MediaCodecAudioRenderer configures the MediaCodec to not downmix audio only if spatialization can be applied. This way, decoders who are downmixing by default are left doing so when spatialization cannot be applied. The renderer re-initializes the codec when spatialization properties change mid-playback.
