Why dsp use %7 while only main menu music play. There no any audio process on music channel. I can’t understand. How Fmod use this dsp?  
Also small level bars(top of fader and process zone) should change while top channels drag left or right in mixer view .  
Unity audio is disable but unity profile show %0.4 audio dsp usage.

I’m not entirely sure what you are asking. The 7% is of the mixer thread, another way to think of it is a percentage of realtime. For example if it takes 5ms to produce 10ms of audio, you are at 50% since you have to produce chunks of audio at regular intervals. That’s why it glitches when it goes over 100%, i.e. it took 12ms to produce 10ms of audio, so you’re 2ms late.
