My Pixel 4A with Poweramp Pro build 939 had the exact same problem after the phone updated to Android 13. I contacted the developer, who said he was aware of the issue and was working on it. I reverted to my backup music player, then found this thread with suggested workarounds. I tried them and Poweramp works fine again!
I did both suggestions at once so I cannot say which of them fixed it or if both are necessary. In any case, I launched Poweramp, clicked on the hamburger icon and did the following:
Settings -> Audio -> Output -> clicked Restore Defaults
Settings -> Look and Feel -> Notifications -> clicked Restore Defaults
I have never changed the audio output or look and feel settings so I don't understand why this worked -- they were presumably already the factory defaults. But this DID work, so I'm happy. Thank you!
