1. ZTE Axon 7
2. Android 7.0 (A2017UV1.1.0B15)
3. AKM AK4961 and AKM AK4490EN
The axon worked with Android 6.0/6.1 but the new 7.0 seems to have broken it. I'm sure you know why, just wanted to let you know. Hope it's an easy fix as I love Poweramp and when I went to use it after the update I could immediately notice the difference.
