Edit: Issue solved. Lenovo had Dolby sound enhancement software installed. I deinstalled it, but the audio enhancement setting stuck and couldn't be changed anymore. That prevented Equalizer APO from working properly.
Reinstalling Dolby software and deactivating the audio enhancement made E-APO work.

Great to hear, John.
Btw. It seems your second post awaits moderation by the Equalizer APO project owner. In other words, we can't see its contents.
