Have tried several music equalizers. All load OK on N7, interface seens fine, but cannot get any to affect music in earphones. Tried this with several program sources - WinAmp-Free, Netflix, Youtube, ever a sample song that came packaged with Equalizer. Must be an N7 setting problem, or an Android 4.1 problem.
Yes, I've set N7 to the equalizer I'm using, under Settings> Sounds> Music Effects> my equalizer.
Any advice on this?
If you are using an equalizer that is working correctly, tell me which one and I'll give it a try.
