@Benno1988 - I could be wrong but I believe the EQ only works with local files and within the Shanling player app. I don't believe it's a global setting,
@Shanling - I find it interesting that the team managed to figure out how to put a working EQ in your own app but did not include the ability to have an EQ work from a third party app system wide. Couldn't they just look at the code for what they did to make it work in their own app and apply that to allow third party EQ apps on a system wide setting?
