I installed PEQ 983 in my android 12 car device,but it has a strange promble for me. If i change volume with PEQ volume knob, it is always back to 50% after press system volume key or play the next song . I try to turn on/off DVC,but it doesn't help to fix this. I have the same problem with Poweramp until upgrade to v981. I don't use them together by turn on music FX. I only use PEQ with kkbox/youtube/radio. How can i fix it?
