Constantly getting "Failed to play file" errors on OnePlus 7 Pro in Poweramp Release Discussion Posted July 10 12 hours ago, maxmp said: @tman450 are you on 838 build? Thanks! @atomi Hi-Res is usually not supported by system wide equalizers. If can say for sure if you provide your device/android info. Thanks!

I have been able to get it close as possible to the way it soundsed before, but still i miss about half of the bass from before. Reason being that it gets really muffled before it gets even close to the settings that i had when high res audio was working.
