Recently I got a Maceton WM4BE Bluetooth receiver which supports AptX. On my Sony Xperia Z5 with Poweramp (version 2.0.10 build 588) the sound quality is very good but with other apps (Sony music player, Spotify, YouTube) it sounds too loud and crackles quite a bit. I've checked my Sony audio settings and even changed to safe mode, but apps other than Poweramp still sound bad...
So I'm wondering exactly what Poweramp does differently to Bluetooth audio compared to other apps? Has anyone had similar experience with the Xperia Z5? Turning Bluetooth DVC on increases the volume in Poweramp, b
