I have a problem with Allwinner V3s SOC with the audio module. When I start playing anything I hear a short spike in speakers and when playing over the same or similar big spike. I feel that before and after the audio module inside is turned on and off. How can I prevent it by for instance setting the audio module to turn on constantly? How to avoid this short huge spikes?

Thanks
