Hi! I have noticed same weird bug quite ago... As in the topic AAC files with 48 kHz aren't detected properly by Poweramp. I can play them by pressing on them one by one in file manager. The only problem here is when I want to skip opened song. It shows that there is to many corrupted files... I've rescanned folders with music and still can't find them. Music is stored on SD card. I've done what i could so I ask for help here. Thanks in advance.
Good news. Sekula925 found workaround for it. Disabling skip short tracks solves problem with showing them in music library.
On my Nexus 7 running Android (4.4.2 build KOT49H) Poweramp (2.0.9-build-554-play) plays 44KHz WMAs, but not 48KHz (such as radio / TV recordings). My Samsung Galaxy S4 mini plays both. Do I need an additional codec or something?
