// TODO: send beforemix event (in ~2,6 ms before mixing)

// The hardware heartbeat interval of libaudio is ~5.3ms.
// As soon as one interval starts, libaudio waits for ~2.6ms (half of the interval) before it mixes the audio.
// There are 2 different types of games:
// - Normal games:
// Once the audio was mixed, we send the CELL_AUDIO_EVENT_MIX event and the game can process audio.
// - Latency sensitive games:
// If CELL_AUDIO_EVENTFLAG_BEFOREMIX is specified, we immediately send the CELL_AUDIO_EVENT_MIX event and the game can process audio.
// We then have to wait for a maximum of ~2.6ms for cellAudioSendAck and then mix immediately.
