Just checking, but you are using the latest build 704 aren't you? (it's a bit hidden at the bottom of the 703 page)

Hey Andre,
I got the same Issue and was on 703 and now tried 704 for ~1 week. at first it "seemed" to work, but if I unlock my phone and Poweramp opens directly it shows me the "Cant use Hi-Res Output, reverting to standart" - popup.
Requests for Hi-Res Support (please state which build of Poweramp you are using)
